Folks,
IGNITE-4922 JDBC Driver: renew thin client based solution:
On 2.1 the functionality of the new thin client JDBC driver will be
between deprecated Ignite thin JDBC and Ignite JDBCv2.
1. The most functions of SQL query (include DML) are implemented and
ready for review;
2. The most functions of JDBC metadata are implemented and ready for review;
3. Transactions, batching, streaming, blobs, scrollable / writable
cursors will not be supported in 2.1.

Folks,
We are almost reached proposed feature-complete date (June 2), Could you
please share current status of your major features?

Looks a little tight. Let's hope we can make it.

Well, let me propose the following milestones for 2.1 release then.
Code freeze: June 2nd.
Final QA and benchmarking: June 5 - June 8
Voting: ~ June 9
Release: ~ June 13
Also I heard H2 has to be released once again to support Ignite’s CREATE
table command. Think that we should talk to H2 folks to make it happen in
June 22nd - June 2nd time frame.

As for .NET, I would propose to concentrate on peer deployment
(IGNITE-2492)
and related stuff, like IGNITE-1894 .NET: Delegate support in the API
via
extension methods.
SQL Dependency does not look important to me, we can reschedule it for
later versions.

Vyacheslav, I think it is worth the research, but you should always
keep
data querying and indexing in mind. For example, I don't see how
by-page
compression will solve it.

Dmitriy,
I'm researching a best way for this future.
At the moment I found only one way (querying and indexing
compatible),
this
is per-objects-field compression.
But there is a good proffit only for long strings or fields with
large
objects.
Maybe it makes sense just to introduce compression for string fileds.
I'm researching the new page-memory architecture as applied to
by-page
compression.

Denis,
The described roadmap looks great!
Additional, I vote for introducing an ability (OOTB) to store
objects
in
a
cache in a compressed form.
This will allow to store more data at the cost of incriasing of CPU
utilization.
One of the problems with compression is indexing and querying. How
do
we
index the data if it is compressed?

Igniters,
Let me start a discussion around the scope for 2.1 release.
In my vision the main direction of our ongoing efforts should be
implementing in life a use case of Ignite as a transactional
distributed
SQL database and HTAP platform. The current use cases (database
cache,
data
grid, micro services platform, etc.) will be supported as usual,
no
changes
on that frontier.
Keeping this in mind, the roadmap needs to include essential SQL
related
features as well as disk based capabilities, MVCC support,
advanced
DDL
implementation and so on so forth. This is for Ignite as a SQL
database.
Next, Machine Learning will be a great addition to Ignite as an
HTAP
platform offering. This is why we should keep investing our time
and
resources in that recently released component.
Having this said, I see the scope for 2.1 release this way:
1. Distributed Persistent Store - if the donation is accepted by
ASF.
The
decision is to be done in separate discussion. W/o the store
Ignite can only be used as In-Memory SQL database.
2. SQL Grid:
- CREATE & DROP table commands: https://issues.apache.org/
jira/browse/IGNITE-4651
- Renewed JDBC driver: https://issues.apache.org/
jira/browse/IGNITE-4922
- Collocation based routing of SQL queries:
https://issues.apache.org/
jira/browse/IGNITE-4510,
https://issues.apache.org/jira/browse/IGNITE-4509
-
3. .NET:
- Peer-class loading: https://issues.apache.org/
jira/browse/IGNITE-2492
- SQLDependency: https://issues.apache.org/
jira/browse/IGNITE-2657
4. C++:
- Compute Grid: https://issues.apache.org/
jira/browse/IGNITE-3574
5. ML Grid:
- Linear regression algorithms: https://issues.apache.org/
jira/browse/IGNITE-5012
- K-means clustering: https://issues.apache.org/
jira/browse/IGNITE-5113
Please join the thread and share your thoughts, ideas and
concerns.
