Re: Parquet Sync meeting notes - April 23 2024

[Steve Loughran]

In my vector  IO PR it was raising false positives about a new class.

Maybe the process should be something like "submitter needs approval for
extra exclusions"

more troublesome: once a release has shipped, those exclusions should be
stripped from the master branch,
as then a regression is a genuine failure

Let me take a look at the exclusions of japicmp. Will try to remove
them as much as possible.

Re: Parquet Sync meeting notes - April 23 2024

[Gábor Szádovszky]

Sorry, I was not able to attend the meeting. Let me put some notes here:

2. We have been fighting with compatibility issues for a while now. That's
why we introduced japicmp. I can see many exclusions in the master pom. I
think we should investigate if these exclusions cause any issues before the
next release. We should avoid excluding code from the compatibility checker
even if it seems reasonable because they tend to be kept there from release
to release.

3. Let's call it parquet-mr 2.0. "Parquet" might be confusing since this
mailing list is used for both parquet-mr and parquet-format.
I think the main requirement for parquet-mr 2.0 would be to have it
"standalone". The core should contain an API that is able read/write
parquet files at different levels. It should be released in a way that it
does not bring any dependencies. (What is required should be shaded.) We
can even start developing the new API in a separate module under parquet-mr
1.x, so our clients can play with it and give feedback.

[Claire McGinty]

Great news on 1.14 getting ready for release! It's a little last minute,
but I cleaned up a draft I've been working on for supporting an
Array#Contains predicate and opened a PR
. It is a lot of code to
review, but surprisingly didn't require any breaking changes. I'm wondering
if it's feasible whether this feature could make it into 1.14.0 :)

Best,
Claire

Re: Parquet Sync meeting notes - April 23 2024

I will defer here as per Parquet community Parquet V2 encoding is not final yet 
so they haven’t make it official. I have no clue how pyarrow is supporting it ?
I thought  parquet used by pyarrow and Spark should have same flavor but 
unfortunately it is not which is very concerning. Spark doesn’t support write 
in Parquet V2 and pyarrow do support in V2.

Re: Parquet Sync meeting notes - April 23 2024

[Gang Wu]

I would expect so. parquet-mr has a complete implementation of all v2
encodings
and some other Parquet implementations (e.g. Apache Arrow C++ and arrow-rs)
have already supported most (if not all) v2 encodings for a long time.

Parquet Sync meeting notes - July 2023

[Xinli shang]

7/25/2023

Attendees (Gidon Gershinsky , Gang Wu, Chao Sun, Xinli
Shang, Jiashen Zhang)

Review data masking

   1.

   The current design is to implement on the reader side and it is
   lightweight
   2.

   When KMS returned access denied and the session-based flag is enabled, a
   null value is returned instead of the original value.
   3.

   Relying on the KMS access denied has a few issues
   1.

  Expense because it is RPC calls
  2.

  There are different KMS and the retuning error might be different

Add a column-wise key/nullify flag just like we did in the column encryption
.
By doing this, we don’t need to contact KMS

Parquet sync meeting notes - April 2023

[Xinli shang]

Hi all,

Here is the meeting notes for today's Parquet sync meeting.


4/28/2023

Attendee  (Shenxuan Liu, Fokko Driesprong, Gang Wu, Jiashen Zhang, Xinli
Shang )

   1.

   Post-release 1.13.0
   1.

  Iceberg upgraded to 1.13.0 bumped the Hadoop support to Hadoop 3 but
  we didn’t notice since we don’t run CI against hadoop 2. This has been
  fixed in #2290 <https://github.com/apache/parquet-mr/pull/1083>.
  2.

  Some small changes (#1073
  <https://github.com/apache/parquet-mr/pull/1073> and #1074
  <https://github.com/apache/parquet-mr/pull/1074>) to make Flink use
  the ParquetMR without having Hadoop on the classpath.
  2.

   In Velox, we store/cache files locally, then we could see a bottleneck
   in the parquet itself.
   1.

  Use SSD to store the local file 3G bytes/sec, For decompression, it
  is 200M/Sec.
  2.

  The current Parquet reader is designed for remote reading.
  3.

  There is a trans-compression
  
<https://github.com/apache/parquet-mr/blob/master/parquet-cli/src/main/java/org/apache/parquet/cli/commands/TransCompressionCommand.java>
  API you can use to speed up,  about 20x faster
  4.

  ZSTD is recommended
  3.

   Data masking Parquet-2223
   <https://github.com/apache/parquet-mr/pull/1016>
   1.

  The code is incomplete. It is needed to hide the columns in the
  schema when it is hidden. And we also need to mark it as hidden.

Parquet Sync meeting - July 26 2022

[Xinli shang]

Attendees ( Gidon Gershinsky, Xinli Shang, Tim Miller)

   1.

   Release 1.12.3
   1.

  Post release - no issue reported.
  2.

   Parquet Cell-level encryption

  a. What if the user only partially has the keys but
not all the hidden columns? Should we throw an exception or filled out with
'null'?
  b. It needs more discussion and we can continue in
the design doc.

   1.

   Parquet-2069 : Fix some
   avro schema issue. Generally, Avro schema conversion is a problematic
   area and we need some risk control.
   2.

   Parquet-2126 :
   thread-safe compressor/decompressor. Close to merge but need some more
   thinking on the thread exit scenario.

Xinli Shang

Updated invitation: Parquet Sync @ Monthly from 9am to 10am on the fourth Wednesday from Wed Oct 27, 2021 to Tue May 24 (PDT) (dev@parquet.apache.org)

   1.

   Cell level encryption
   1.

  Formal design
  

  is sent out
  2.

  We choose the 2nd option - splitting columns because it doesn’t need
  specification change
  3.

  Implementation is going on
  4.

  Create a feature branch for review
  2.

   Column resolution by ID (pr
   )
   1.

  The ‘field_id’ in the schema is used.

  Uniqueness might not guarantee to be used by column resolution with
  ID. We might need a place to remember a flag that this Parquet file is
  column id resolvable
  3.

  Concat tool might be a problem
  4.

  Need some help from Iceberg
  3.

   Parquet writer for Iceberg (Adding a new constructor)

Curious if more notes, or discussion around the two points above will
happen on the mailing list?  Or are there relevant JIRAs?

Thanks,
Micah

Parquet sync meeting notes - April 2021

[Xinli shang]

4/27/2021

Attendees: Xinli Shang, Gábor Szádovszky, Gidon Gershinsky, Xin Dong, Ryan
Blue, Q. Xie

   1.

   Parquet 1.12.0 post release issues:
   1.

  Parquet-2027 - Page offset issue. Fixed.
  2.

  Parquet-2026 - Not allowing empty file anymore
  1.

 What are the data of empty file looks like?
 1.

They are 0 rows files.
2.

 What are they used?
 1.

 In some cases, they could be used as a placeholder.
3.

 The previous release didn’t make it clear as a supported feature.
 If we allow this in the future, we should document this.
Gabor will chat
 with the owner if they can fix and contribute.
 2.

   INT-96 issue: Is it possible to fix it? For the read path, we already
   have a configuration. So far it seems not easy for us to fix as it could
   introduce several issues.
   1.

  Gabor will open a Jira ticket and investigate a little more to get a
  sense of how complex and how risky it is. Once we have that
information, we
  can discuss it next time.
  3.

   Provider-aware compression codec - PARQUET-1886
   1.

  If we can make it independent of Hadoop API, it could be better.
  Let’s have a design for that. Make it configurable instead of implicitly
  looking up because that could introduce runtime error.
  4.

   Iceberg related discussion
   1.

  Testing is going on with Iceberg for Parquet 1.12.0.
  5.

   Null data masking
   1.

  Null masking implemented in Parquet and it doesn't need to re-write
  the data. It can be contributed to open source.

Parquet sync meeting notes Jan 26, 2021

[Xinli shang]

Hi all,

Attendees: Xinli Shang, Gábor Szádovszky, Gidon Gershinsky, Jason
Alterkruse


Topics:

   1.

   Parquet column encryption
   1.

  The ported code in Presto will be open-sourced soon.
  2.

  Crypto factory could be changed when new use cases come in(Gidon).
  2.

   Parquet-mr 1.12.0 release
   1.

  The higher version of Avro only has unit test diff. We should go
  ahead to release.
  2.

  Check with Spark community for the Spark Avro issue - Xinli
  3.

  There are still a lot of open PRs. We want owners to indicate should
  those PRs be included in 1.12.0.
  4.

  Will issue an RC0 release soon - Gabor
  3.

   Core features definition
   1.

  Send emails to all PMCs - Gabor
  4.

   Deprecation of summary files
   1.

  There is a discussion in the Iceberg community for summary files.
  Those files could be still useful in some cases (Jason).
  2.

  At least in Parquet 1.12.0, we will leave it as is while the
  discussion is still going on. Maybe we can add a switch to turn
it on/off.


Please let me know if you have any questions.

Re: Parquet sync meeting 11/24/2020

[Gidon Gershinsky]

Thanks Xinli,

A slight correction re 2.1: The recent improvements / pull requests are in
the Java version, parquet-mr. But the ideas for some of them indeed came
from our work with the Arrow teams, that develop a C++ version of parquet
modular encryption.

Cheers, Gidon

[Ryan Blue]

Sorry I wasn't able to make it to the sync today. I should be able to make
it to the next one and we can talk about getting some of Iceberg's changes
upstream.

Parquet sync meeting 11/24/2020

[Xinli shang]

11/24/2020

Hi all,

Attendees:

   1.

   To solve Parquet upgrading with Avro version issue, should we release
   Parquet Avro with a separate release?
   1.

  For uprading Avro from1.8 to 1.9, Parquet only have unit test change
  and parquet-cli and user can excluce avro from Parquet
  2.

  The long-term still benefits if we can separate but it is not easy,
  for now, it is not required.
  2.

   Column Encryption
   1.

  C++ version has several PRs (improvements) recently.
  3.

   Data masking


   1.

   Some upper layer can develop their own data masking easily.
   2.

   We might think about some simple tools other than executing them in
   Parquet.
   3.

   Developed null data masking in Parquet and it works now. Open a Google
   doc and we can discuss from there.


   1.

   Parquet 1.11.x adoption to Presto
   1.

  PR  is created but it
  has a unit test failure.
  2.

   Parquet 1.11.x feature adoption to Iceberg
   1.

  Iceberg meeting notes
  

  for discussing this issue.
  2.

  Issue summary and proposals
  


  3.

  For having Parquet V2 API to support Iceberg, if we do that, then
  makes sense to have vectorized API with Parquet V2 API. Let’s bring other
  PMS/commuters to discuss for the next community meeting.
  3.

   Parquet 1.12.0

a. Will cut RC release soon

Please let me know if you have any questions.

Parquet sync meeting notes - Oct 2020

[Xinli shang]

10/27/2020


Hi all,


Attendees:  Michael, Gidon, Gabor, Xinli, Cao Sun

   1.

   Column Encryption
   1.

  Parquet-1396 is approved and will be merged.
  2.

  So far, all the planned changes around column encryption are done!
  3.

  Data masking
  1.

 Set up a call with Sri and Gidon for it.
 2.

 PR  for replacing
 the column with null is in the review.
 2.

   Questions around Parquet v1 and v2
   1.

  Encoding is not bounded to v1 or v2
  2.

  Not clear on v2 roadmap
  3.

  Documentation of v1 and v2 - Owner: Michael
  4.

  Discussion for retiring of V2
  3.

   Parquet 1.11.x adoption to Presto
   1.

  PR  is created but it
  has a unit test failure
  4.

   Parquet 1.11.x adoption to Iceberg
   1.

  Upgraded to 1.11.1 now
  2.

  Integrating the Column Index feature to it. See some issues and Xinli
  is working on it.
  5.

   Parquet 1.11.x adoption to Spark
   1.

  Parquet 1.11.x introduced a new version(1.9) of Avro which removed
  some APIs. It breaks the upgrading.
  2.

  Solutions - Fix Avro in Hive
  1.

 Upgrade to 1.9, attempted but introduced a lot of issues.
 2.

 Replace deprecated API call in Hive with a new API. Hive remains
 1.8 of Avro. This has to be in Hive 2.3 and upgrade Avro from
1.7 to 1.8 of
 Avro.
 3.

  Tracking ticket
  1.

 https://issues.apache.org/jira/browse/SPARK-27733
 2.

 https://issues.apache.org/jira/browse/SPARK-26346
 6.

   Parquet 1.12.0
   1.

  Some companies want to adopt column encryption which is only
  available in Parquet 12.
  2.

  Parquet 1.12.0 will be on Avro 1.10. Need to know if this is a
  problem. Chao will try it out.


Please let me know if you have any questions.

Parquet sync meeting notes - 9/22/2020

[Xinli shang]

9/22/2020

Hi all,

Attendees:  Ashish Singh, Julien, Gidon, Gabor, Xinli

   1.

   Column Encryption
   1.

  PRs are all merged.
  2.

  Data masking
  1.

 This feature should have top-down approach starting from service.
 Maybe we can start with parquet-tool.
 2.

 Reducing the storage overhead for data masking - There are some
 thinkings about different compressions and tools.
 3.

 Testing: Write more tests and test with real data usually are good
 approaches. Maybe we can ask some 3rd parties that don’t know
this feature
 to have test by looking at the specification. Another way is to have
 interoperability tests between C++ and Java implementation.
Gidon has done
 some in his work. It would be great if we have automation for
it to test
 more.
 2.

   Parquet 12 release
   1.

  Created Jira ticket to release.
  2.

  Concern for the adoption of Parquet 1.11.0 because of Avro
version. Action
  Item(Owner: Xinli) - Bring in people dealing with this upgrade effort
  to the next meeting to discuss the next step.
  3.

   Parquet-313: Implement 3 level ist.
   1.

  This is a good initiative. It is a little hard for current committers
  to review because we don’t use that or don’t have knowledge of
that. Check
  if somebody from Twitter can help with the review & verification. Action
  Item(Owner: Julie) Julie will try to find someone.
  2.

  Use a flag in the code to make it optional to reduce the risk.


Please let me know if you have any questions.

Meeting notes for Parquet sync (July 2020)

[Xinli shang]

Attendees: Gidon, Gabor, Fokko, Xu, Sri, Xinli



   1.

   Column Encryption
   1.

  PR 800  - This is to
  merge to master and it is being reviewed.
  1.

 One comment is about CRC. Since the encryption algorithm AES-GCM
 already has an integration check, doing CRC is redundant.
 2.

 The behavior “CRC is enabled by default in writing path” will not
 be changed even when AES-GCM is used. This is because CRC calculation
 overhead is very small according to our earlier tests, and changing
 behavior may break something.
 2.

  The PR  for
  Parquet-1396 will be moved to the master branch after PR 800
   is done.
  2.

   Parquet 1.11.1 release.
   1.

  Additional fix(Parquet-1684
  ) to be added?
  The conclusion is no after the discussion. This is not a regression in
  Parquet11 and the change itself is not low risk.
  2.

  Rolling out the Spark is still blocked. But downgrading the Avro
  version in Parquet is not an option.
  3.

   Parquet 12 release
   1.

  After encryption is done, Gabor will create a Jira to start the
  process.
  4.

   Proposal for CompressionCodec Provider-aware Compression Codec (doc
   

   )
   1.

  PR-803  need to be
  reviewed
  5.

   Data masking
   1.

  After column encryption is done in master, we(Xinli, Gidon, and Sri)
  will start the conversation.


Please let me know if you have any questions.

Parquet sync meeting notes - 4/28/2020

[Xinli shang]

Hi all,


Please find the meeting notes below. I apologize for sending the meeting
password late and that caused some people cannot join the meeting. I wasn't
aware of the Zoom's change that forces everybody except for the meeting
owner to input the password. I have updated the meeting invitation and
included the password.


4/28/2020

Attendee:  Xinli, Gabor

Topics:

Column Encryption

   -

   In the basic parquet encryption layer, two pull requests are left: PR-776
    (ready for review), and
   PR-782 (focused on testing interop with parquet-cpp, can be reviewed after
   initial round of 776 reviews).
   -

   The next step is to work on key management tools and Parquet-1396
   (schema controlled encryption).

Parquet-11 Release

   -

   Spark-26346 /
   PARQUET-1774 : There
   is a finding in Spark. Gabor is waiting for the Spark community to verify
   the fix of Parquet-1174. No response from Spark yet.

Parquet sync meeting notes

[Xinli shang]

3/24/2020

Attendee:  Walid, Gabor, Xindong, Gidon, Shrikumar, Xinli

Topics:

Column Encryption

   -

   PR-769  is being
   reviewed. Gidon/Xinli just addressed the feedback this morning and Gabor is
   going to have another look.
   -

   Gidon has the code that encrypted column indexes, waiting for PR-769
    to be merged and then
   create PR.

Parquet-11 Release

   -

   Spark-26346 /
   PARQUET-1774 : There
   is a finding in Spark. Gabor is waiting for the Spark community to verify
   the fix of Parquet-1174. No response from Spark yet.

Bloom Filter:

   -

   Walid created the PRs for Union/Intersection APIs
   -

  Gabor: We would like to see use cases of them before we can add them.
  -

   Bloom Filter configuration
   -

  Comments: Have a page to discuss the configuration

Parquet-1804:

   -

   Xindong: Some performant compression methods utilizing hardware can
   accelerate compression. We want the parquet-mr to support a customized
   compression method.
   -

   Concern from the community: We already have some issues between
   parquet-mr and parquet-cpp as an example. If we open the door for users to
   customize their own compression, then more compatibility issues could
   happen.

Parquet Sync Meeting Notes

[Xinli shang]

Hi all,

These are the meeting notes for today's Parquet community sync.

1/29/2020

Attendee:  Brian, Xinli, Gabor, Gidon, Walid


Topics:

Column Encryption

   -

   https://github.com/apache/parquet-mr/pull/614 need to be merged.
   -

   Still waiting for Parquet 11 release.


Parquet-11 Release

   -

   There is a finding in Spark and working on it.


PARQUET-1681 


   -

   This is a severe issue. Some types of Avro schemas(like this
   
)
   are not compatible with themselves after converting to Parquet. This causes
   the data cannot be read. The fix is ready and a PR will be created for
   review.

Re: Parquet sync zoom - invalid meeting ID

[Xinli shang]

Sorry for the meeting ID issue. I don't know why this same ID worked for
the last two meetings but not today. I will send out another invitation
soon targetting for early December as a makeup.

Just Julien and me in the meeting today and we briefly talked about the
current outstanding tasks. We can talk them in more detail in the makeup
meeting.

The same is happening to me. Additionally, one of the toll-free phone numbers 
did not pick up.

Re: Parquet Sync - 10/17/2019 - Meeting Notes

[Gidon Gershinsky]

A slight correction re C++. I said the following
C++ work is near completion/merge. Deepark has reviewed it and made
additional changes / refactoring.

Parquet Sync - 10/17/2019 - Meeting Notes

[shangx]

10/17/2019

Attendee:
Gidon
Gabor
Ryan
Karfiol
Xinli

Topics:

Column Encryption
For C++ version, Gidon worked with Deepak to have reviews going on.
For Java, we are blocked on the Parquet-11 release. Gabor proposed to have  
branch the Parquet-11 and then merge later. But we would need to be in  
master as the final step.


Bloom Filter
Next step is to wait for the Parquet-11 release

Parquet-11 Validation
Ryan - the release can go ahead without me if there are enough PMCs
Gabor - I will try to push this effort in a couple of weeks

Ongoing Parquet Work
There is some work to create PR shortly to optimize Parquet usage of byte  
buffer, ParallelIzation, S3 reading, etc.

Re: Parquet Sync - Meeting Notes

[Gidon Gershinsky]

Hi Xinli,

Regarding the parquet-cpp encryption - there are no integration errors. A
number of pull requests are merged by now; the remaining code has been
reviewed and updated; the only outstanding question (how/when to turn off
OpenSSL getting included in Arrow) had been addressed by the Cpp leads and
will be resolved soon.

Cheers, Gidon.

Parquet Sync - Meeting Notes

[shangx]

Hi all,

This is the meeting notes that I took. Feel free to add or correct it if  
something is missed or wrong.


9/19/2019

Attendee:
Xinli Shang(Uber)
Gidon Gershinsky(IBM)
Jim Apple (Netflix)
Nandor Kollar, Gabor, and several other Cloudera folks
Julien Le Dem (WeWork)
Deepak (Vertica)
   Please add if you are missed.
Topics:
Column Encryption
   Parquet-format has the specification merged.
   One PR is merged into parquet-mr, the second is being reviewed.
   For parquet-cpp, we still have some integration errors.
   Xinli backported the encryption code to parquet 1.10.1 to mitigate the  
risk. We can wait for 1.11.0 release before deciding should public  
community should do that.


Bloom filter
The spec has been checked in to parquet-format.
Will continue the validation of the correctness on parquet-mr(feature  
branch) and parquet-cpp(master branch? some code like reader/writer not in  
master branch yet).
Netflix has done enough testing on performance. The remaining tests are  
mainly for correctness.

There are unit tests and integration tests that cover.

Parquet-format 2.7.0
Releasing of parquet-format is slow now. We need the release before  
checking into parquet-mr master.
There are several options. We prefer option 3 that is to release bloom  
filter and parquet encryption together in 2.7.0.

3 PMC voted in this meeting +1 for the option 3.
Ryan can help on the release, signing keys etc.

Remove old Parquet modules
Hive modules  - sounds good
Scooge  - Julien will reach out to twitter
Tools - undecided - Cloudera may still use the parquet-tools according to  
Gabor.

Cascading - undecided
We can change the module as deprecated as description.

1.11.0 Release
Column index validation -   Need Ryan to review it.

Someone is proposing byte_stream_split encoding in the mailing list
Ryan made a proposal and the owner just replied to try the proposal and get  
back.


  7. Merge Parquet and ORC
Ryan and Owen had a talk in ApacheCon regarding merging ORC and Parquet.
There are a lot of benefits to doing that but also a lot of work. Overall,  
people in this meeting support this effort.

Ryan can start socializing this effort.

Xinli Shang (Uber)

Re: Parquet Sync Meeting Notes

[Jim Apple]

I believe this has now been both voted on a few months ago and approved by 
Zoltan last week.

If someone could merge it, that would get us one step closer to a 
parquet-format release.

Re: Parquet Sync Meeting Notes

[Xinli shang]

Gidon pointed out that the encryption parquet-format PR is the one below

Parquet Sync Meeting Notes

[Xinli shang]

7/17/2019

Attendee:

Ryan Blue(Netflix)

Jame(Netflix)

Gidon Gershinsky(IBM)

Steven(Yelp)

Deepak and several other folks (Vertica)

Xinli Shang(Uber)

Junjie Chen

Topics:

   1.

   Column Encryption
   1.

  Gidon:
  1.

 C++ version code review: Have addressed all feedbacks. The last
 step is testing. Hopefully tomorrow the testing can be done.
 2.

 Reviewed bloom filter design from Parquet encryption perspective.
 It is straightforward.
 3.

 Not much done on Java version Parquet side. Worked with Xinli to
 fix several issues.
 4.

 Found throughput issues in Java and fixed it.
 2.

  Xinli:
  1.

 Gidon sent out a design which consolidates different ways of
 deploying parquet encryption, but not much attention is
gained from the
 community. Please have a look if you are interested in.
 2.

 There is a discussion about unifying table properties in
 HMS(HIVE-21848) for both ORC and Parquet column encryption.
Please chime in
 if you have a concern.
 3.

 Java version parquet-mr PR review is being slow. How do we move
 faster? We need more people to review it.
 1.

https://github.com/apache/parquet-mr/pull/613
2.

https://github.com/apache/parquet-mr/pull/614
3.

https://github.com/apache/parquet-mr/pull/643
3.

  Jim
  1.

 What is blocked on the parquet-mr review? We need more people to
 review it. There is a lot of PR now.
 4.

  Deepak
  1.

 Does the parquet encryption work with Hive?
 1.

Yes, we have tested it(xinli).
2.

 Also have questions about table properties definition.
 1.

HIVE-21848(xinli)
2. Bloom filter
  1.

  Junjie Chen
  1.

 We need one more PMC vote
 2.

  Ryan
  1.

 I will have a look next week. Were the issues raised earlier
 addressed?
 1.

Yes(Junjie)
2.

 Parquet-format should be considered as upstream for parquet-cpp
 and parquet-mr that are implementation.
 3.

 We need Encryption specification merge to parquet-format ASAP,
 then bloom filter. Otherwise, parquet-format will depend
parquet-cpp and
 parquet-mr, which is not right.

   https://github.com/apache/parquet-format/pull/68

   https://github.com/apache/parquet-format/pull/142
   1.

  Xinli
  1.

 Is parquet-format 2.6 + encryption compatible with parquet
 2.7(encryption + bloom filter)?
 1.

By design, yes(Gidon)
2.

 Please add Xinli for testing if we have a prototype for bloom
 filter to make sure they are compatible.



   1.

   Parquet-1.11.0 Release Validation
   1.

  Ryan
  1.

 Both Ryan and Zalton are very busy. No progress so far.
 2.

 We need to write a test to make sure the data write/read are
 correct.



   1.

   Remove old Parquet modules


   1.

   Ryan
   1.

  No time. If somebody has time to do it, go for it.

Re: Parquet Sync - Meeting notes

[Zoltan Ivanfi]

Hi,

I would like to add the following to the notes for topic "1. key signing":
- Zoltan brought up the question of whether and how PMC-s from the US
could remotely sign the keys of committers/PMC-s located in Europe.
- Julien and Ryan commented that for the purpose of signing releases
it is not really necessary for the signer's key to be in the web of
trust as long as it is in the central KEYS file (especially if the
signers participate in Parquet Syncs discussing the RC, thereby
implicitly confirming their ownership of that signature).

Br,

Zoltan

Re: Parquet Sync - Meeting notes

[Xinli shang]

Hi all,

This is to follow up of the meeting notes below. I created Jira ticket
PARQUET-1396  and the
design can be found here
.
The recorded video  in Hadoop
Contributor Meetup can also help reading the design. Please share your
feedback by commenting on the design doc.


   1. On top of Gidon’s change, we introduced a plugin/interface to Parquet
   to activate encryption and build up encryption properties. Currently, we
   implement its schema driven implementation, but it can be implemented in
   another way too. I will send out the design soon.

Parquet Sync - Meeting notes

[Xinli shang]

4/30/2019

Attendee:

Zoltan and Several other folks(Cloudera)

Brian (SaS?)

Ryan Blue(Netflix)

Julien(WeWorks)

Wes McKinney(Ursa Labs)

Gidon Gershinsky(IBM)

Steven(?)

Anikt(?)

Deepak(?)

Xinli Shang(Uber)


Topics:

   1.

   Key signing issue
   1.

  Zoltan/Julien/Ryan:
  1.

 We already have email exchange of this issue.
 2.

 In the past, it is done in person. But it is OK to sign each other
 via video conference. We can do a video session of signing keys.
 3.

 It is painful to do this every release



   1.

   Column Encryption
   1.

  Gidon:
  1.

 C++ version progress well. It is pretty much done.
 2.

 Wait for Parquet-1.11.0 release to send out code review
 3.

 Found issues in Java. Worked around it. Will talk to Java
 community.
 2.

  Xinli:
  1.

 On top of Gidon’s change, we introduced a plugin/interface to
 Parquet to activate encryption and build up encryption properties.
 Currently, we implement its schema driven implementation, but
it can be
 implemented in another way too. I will send out the design soon.
 3.

  Gidon:
  1.

 Overall we took a bottom-up approach. We might need another layer
 on top of these to make the adoption easier.
 4.

  Ryan:
  1.

 Different companies can have a different implementation. It is
 good to have a plugin mode.
 5.

  Brian: Question of the key metadata, KMS.
  1.

 Currently, Parquet designs it as a byte array. Depending on the
 implementation, it can be used to record the KMS/Key Metadata.
 2.

   Parquet-1.11.0 Release Validation
   1.

  Ryan
  1.

 Validate the write path of column index - We need to test the
 calculation is correct; Validation is independent. Ryan will
take this task.
 2.

  Brian:
  1.

 Can help some testing in Summer if needed.
 3.

  Steven:
  1.

 What is the test strategy, any fuzzing test?
 4.

  Ryan:
  1.

 We have some random test but not reliable. Inside Netflix, we have
 stable fuzzing test. May need to port some to Parquet.
 5.

  Xinli:
  1.

 We have run a lot of regression test on Parquet-1.11.0. We add
 encryption code on top of 1.11.0 and run a lot of tests. No
new feature
 test of 1.110 but existing features tests are so far so good.
Let us know
 if you want us to add some more tests into our test suite.



   1.

   Remove old Parquet modules


   1.

   Ryan
   1.

  We should remove those old modules if they are not needed
  2.

  Hive module - Seems not used
  3.

  Scrooge module - if it is only used by one company, we might not want
  to maintain it
  4.

  Does anybody still use parquet-tools instead of parquet-cli? Maybe we
  can mark it as deprecated.
  5.

  Open a Jira ticket for it.
  2.

   Julien
   1.

  Twitter may use it. Julien will check with Twitter.
  2.

  We should communicate widely.
