I've merged changes related to IGNITE-426 (Make sure continuous queries
notifications are not missed in case primary node fails
) task.

Can someone please clarify the *exact* release schedule?

I hear that the merges may be completed tomorrow Friday, but the release
will be built next Friday. Is this correct?

I'm finishing my work on the OSGi integration (three modules), which I'd
like to get into 1.5. I'm pretty much done, and I'm just finishing
Javadocs, README, etc.

I also want to create 2 unit tests for the two different classloading
strategies I've built, but it'll require a bit of fiddling with Pax Exam
and TinyBundles.

Thanks Raul! I think the best approach for your changes would be to finish
them up first (including the documentation). Whenever done, I believe it
should be your call, whether you would consider it safe for these changes
to be merged.

[Vladimir Ozerov]

My update about portable micro-optimizations:
- Distributed benchmarks didn't show any statistically significant
difference between my branch and 1282, results are sliiiiightly better. I
believe the only way to feel improvements in serialization is to create
benchmark which loads CPU well. Ignite Yardstick benchmarks cannot do that.
- Tests are fine, so I will merge my optimizations tomorrow.

In addition I am working on several other minor fixes to portables.

[Vladimir Ozerov]

One more update from my side:
- Merged all pending optimizations (*IGNITE-1917*)
- Fixed several minor bugs and performed several small refactorings in
binary serialization.
- Implemented one major optimization in deserialization logic decreasing
amount of reads in footer (*IGNITE-1961*). This finally allowed us to
outperform OptimziedMarshalled in almost all scenarios. Not merged yet,
need to perform more tests.

No blocking issues from my side for now which could prevent IGNITE-1282 ->
1.5 merge.

[yzhdanov]

Guys!

Let's update status info.

1. Data grid performance optimizations.

Most of the optimizations have been merged. However, there are several
pending ones


2. Direct marshalling compactions: communication optimization - Valentin

My understanding is that this will be merged in nearest hours. Valentin, is
that the case?


3. Introduce new binary format - Alexey Goncharuk and Vladimir Ozerov

The work is mostly done and ignite-1282 will be merged to release branch in
several hours. Alexey, please let us know when you are done.

4. Data grid performance optimizations: SQL queries - Sergi and Semyon

The problem here is that cache updates influence throughput of cache
operations. As far as I know Semyon has investigated this and found several
places in code that could cause this. My understanding is that he will
benchmark and merge this fix over the weekend.


Thanks!

[Alexey Goncharuk]

Yakov,

I still see some of the tests fail on TC in ignite-1282 branch. Some of
them are related to branch-local changes, some of them are related to the
latest optimizations that were merged to ignite-1.5 (for example, there was
a deadlock in restart tests introduced by local collection synchronization
in MVCC manager).

I pushed the changes to TC, so I will give another update in a couple of
hours.

[Raul Kripalani]

Igniters,

OSGi integration is basically done. I need to give it another review pass.
I also want to see if I can OSGi-fy the new modules quickly (twitter,
flume, etc).

Meanwhile I've worked on the documentation and it's pretty much done:

*
https://dash.readme.io/project/apacheignite/v1.5/docs/installation-in-apache-karaf
*
https://dash.readme.io/project/apacheignite/v1.5/docs/installing-in-an-osgi-container
* https://dash.readme.io/project/apacheignite/v1.5/docs/introduction

I expect to finish everything by Monday evening CET.

Could someone please review it on Tuesday for merge into 1.5 next week?

Branch is ignite-1270 in case you wanna peek.

Thanks,

Folks,

There is a couple of sporadical hangs in the branch, need more time to
investigate and fix. Will take a look tomorrow SPb time.

Yakov,

I finalized and merged communication optimizations to 1.5 and master.

Guys,

I finalized and pushed ignite-1282 branch (binary object format) into
ignite-1.5. Even though there were no comments from the community around
the design on the latest stages of the development, I encourage community
to take a look at the changes and provide feedback.

Also, while I was finalizing the branch, I fixed some issues that were
introduced by the latest optimizations and merges between ignite-1.5 and
ignite-1282. Even though the TC was good, it does not mean it revealed all
the sporadic test failures, so if you see a suspicious test, please post it
here on in a separate topic.

Thanks!

[Vladimir Ozerov]

Cool! I closed IGNITE-1282.

Guys,

I finalized and pushed branch ignite-1753-1282 with updated
CacheJdbcPojoStore that use new classes instead of deprected
CacheTypeMetadata.

See IGNITE-1753 Rework CacheJdbcPojoStore to new API
https://issues.apache.org/jira/browse/IGNITE-1753

I will also update documentation on readme.io shortly.

Thanks.

Igniters,

I am working on IGNITE-1987 (Make binary marshaller default). I cleaned up
javadoc and examples. Changes revealed some issues related to keepBinary
flag not being propagated to continuous query listeners, I am working on
fixing them. Changes should be finalized within one day.​

[dsetrakyan]

Hi Raul,

Thanks for taking on OSGI integration. I have reviewed the documentation
and it looks good.

At the risk of sounding pedantic, I think this link is best included as
part of some other OSGI documentation page (no?):
https://dash.readme.io/project/apacheignite/v1.5/docs/introduction

Looking forward to seeing a final version.

D.

Hi Raul and Igniters,
I have some comments for your pull request, one or two points. How does it
works do you plan to create a pull request? How can I comment if no,
through the mailing list?
Does this branch is planed to be merge for the 1.5?

Thanks in advance.

Romain.

I personally don't create pull requests as I am a committer. The code is in
the ASF branch ignite-1270 [1].

Parent ticket would be good [2], and only the crowd that's interested get
disturbed (make yourself a watcher).
