Vladimir,
First of all, statements in Java 8 section [1] looks kind of prohibitive
for me. When a new contributor see words "preferred" and "avoided in most
cases" he most likely will not use such features (like I did). If a
statement is not prohibitive in practice it could be at least rephrased.

Hi Igniters,
I am working on cache metrics support for caches with enabled MVCC. As you
may know, during MVCC transaction execution entry versions are written to
storage right away (without deferring until commit). So, it is not obvious
for me if we should update writes count right away or defer
is dirty writes as additional metrics.

Hi team,
I need you opinion again. I wrote some tests for metrics and felt a
confusion with metrics count for the same key update during transaction.
Imagine following case:
BEGIN;
INSERT INTO person(id, name) VALUES(1, 'ivan');
UPDATE person SET name = 'vanya' WHERE id = 1;
COMMIT;

As we know ThreadLocal is an instrument which should be used with great

ThreadLocal which is not needed anymore. In my opinion the best thing (in

Hi Igniters,
I had a look into IgniteDataStreamer. As far as I understand, currently it
just works incorrectly for MVCC tables. It appears as a blocker for
releasing MVCC. The simplest thing is to refuse creating streamer for MVCC
tables.
Next step could be hair splitting of related use cases.

1. It's common and consequently easy to explain and understand.
2. It's quite universal. One can worry that "table" does not describes
key-value storage well.

Hi,
In my opinion there should be only development discussions and
important notifications on dev list. But I must say that I started to

Hi Vladimir,
How do you see a default tablespace configuration in the "bright"

what cases will be there benefits to explicitly configure additional

By the way was the name "tablespace" hand-crafted or it was it

May be I am a little bit late with my thoughts about a command syntax.
How do I see it is going to be used:
1. A user is able to kill a query by unique id belonging only to this query.
2. A user is able to kill all queries started by a specific node.
For killing a single query we must

I would like to understand following. We are going to make TC green.
