Re: 0.2.0 release?

[Marton, Elek]

Quick update:


TLDR; We need RATIS-227/RATIS-228 (and imho RATIS-229) for the 0.2.0 
release.




Current Blocker/Patch Available jiras:

BLOCKER:

RATIS-227 TestRaftWithGrpc.testBasicAppendEntriesWithAllReplication fails
--> No patch, yet

RATIS-228 Handle zero size log_inprogress file
--> Patch available, seems to be ok for me, but not enough experience 
with the file writing. Please review if you have time.


NON-BLOCKER:

RATIS-229 GRpcLogAppender should trigger a heartbeat when appendEntries
Patch Available -> but "need more testing". Seems to be a real problem 
which should be included, question is open about the implementation.


RATIS-230: Improve gRPC log messages
Patch Available -> seems to be ok for me, checkstyle issues

RATIS-222 Handle Error exception when Unassigned Variable is tried to get .
Patch Available --> I think it should be fixed in different location 
with fixing the error handling of the arithmetic state machine


RATIS-218 Optimize heartbeating in Ratis for Grpc protocol
--> Reviewed, response is pending

I agreed that RATIS-227 is a blocker.  Let me ping Kit for fixing it.

Fair enough, I modified the priority of RATIS-227 to blocker. Let's see if
we can get it soon.

In the meantime I created a preview version of the release:
https://home.apache.org/~elek/ratis-preview (NON OFFICIAL ARTIFACTS!)

And requested reviews from the incubator mentors. Hopefully we can start a
vote at the end of this week.

I think we can have RATIS-227 in 0.2.0 release as well. There might be a
possible bug which needs to be fixed.

Re: [RESULT][VOTE#2] Merge RATIS-5 to a new branch and publish the new site

[Marton, Elek]

And finally: https://ratis.incubator.apache.org/ is up and running.

The source code is at the asf-site-source branch and the html files are 
commited to the asf-site branch.


Thank you all the help,

Thank you very much your votes.

The Vote is passed with:

  * 7 of +1 vote (thx Anu, Jitendra, Mukul, Tsz-Wo, Lokesh, Shashikant, 
Arpit)

  * and without -1 vote.

I will merge the source code and the rendered version to the proposed 
branches and open the infra ticket to publish the site.

ps: I read a lot of asf policies to understand binding/non-binding in 
case of an incubator project. Fortunately this vote is passed anyway. My 
understanding is that for an incubator merge vote it's not needed to 
calculate bindig/non-binding separated but any commiter could veto the 
merge.


Anyway, thanks again the review and vote for all of you.

Re: ratis website proposal

[Marton, Elek]

Thanks again,

We addressed all the issues. (the developer specific subpage will be 
created later, we don't have enough content, yet. We plan to add more 
documentation in the next phase.).


If no more suggestions/objections we will restart the vote on the ratis 
dev list.


Thanks your help,
Marton

Hi,

You may want to change the wording under the Source link as you have develop is 
master it could be seen as you are distributing unofficial code to users there.

Just add some words to the effect that this is for development use only and not 
intended for use by the general public and are not part of an official release 
checked by the PMC.


IMO it would be better to have some pages which are clearly aimed at
developers and put such links there.

Some other nits:

"higly customizable" => "highly customizable"

However it might be more accurate to say 'fully' (are there aspects
that are not customisable?)

--- quote ---
Raft is a easily understandable consensus algorithm to manage replicated log.

Apache Ratis could be used in any Java application where a state
should be replicated between multiple instances.
--- quote ---

'replicated log' does not read well.
Does it mean 'replicated log files' or ' replicated logging' or something else?
I'm not sure how 'log' relates to 'a state'?

Also 'a state' should probably be 'state' as the former could imply a
single state.

Still some mentions of 'java'

"Start three Ratis server" => "Start the Ratis server" ?



Thanks,
Justin

contribution

[Marton, Elek]

Hi,

I would like to contribute to Ratis.

I have two proposals:

 1. I would like to create and register JMX beans for every 
RaftServerImpl to display at least the current leader, term, index,...


   I would like to show this information from the (under devepolment) 
Ozone web ui interfaces.


 2. I would like to add a simple Server and Client class to the example 
project. Currently it could be tested only from unit test. I think it 
would be more easily to try out ratis by starting standalon example 
servers with `java -jar...`. (And check on the JMX interface, if 
everything is fine...)



Please comment my ideas, and if agree, add my user 
(https://issues.apache.org/jira/secure/ViewProfile.jspa?name=elek) to 
the contributors group.


Thanks
Marton
