Nikolay,
Thank you for driving it! It is great to establish this process in
practice earlier because it seems that we need to release a Flink
integration soon because Ignite 2.8 is going to be released without
that integration bundled.
As usual we need to decide about versioning and a corresponde

In current implementation the flag does not change if data is kept or
cleared from memory - after deactivation the internal structures are
cleared and only data region is kept allocated. If you add a validation for
this flag, you forbid users to do a rolling cluster restart and

One comment about first choice.
The formulation has one issue from my point of view: Never deprecate
the old APIs unless the new APIs are stable *and released* without
@IgniteExperimental.
Actually we can introduce new stable API and deprecate old API at the
same time without releasing of new API

The statement seems to be correct for cases when we'd like to perform fast
loading and computation and not afraid of data loss.
Performance boost always means we lose some guarantee.
Let's just update the proposal with the explicit warning that reducing
backups to zero may lead to data loss on any

Yes! I’ve already seen people try to use this without awareness that it’s not
production ready.
What happens with the annotation, incidentally? Is it just in the documentation
or do you get a compile-time warning?

Nikolay,
This sounds like a philosophical question :)
By rigid I mean inability to change some properties without whole cluster
restart, and I do think it's bad. I have a good example in mind - the
number of threads running rebalance. Originally, we added a validation
check for this configuration
Hello,
I think the right answer is YES. It should be marked with the new

Agree, let's mark MVCC experimental.
Stephen, the annotation serves as an additional documentation-style marker.
For now there are no compile-time warnings when the API is used.

By the way, is there any reason to have this code in the master
branch? It seems feature is in unsupportable state and just wastes TC
time and our effort to support MVCC related tests.

A little bit more formalism. The thread subject is about API
deprecation in general. But it looks like that discussion boils down
to a replacement of old API with a new one. I suppose there should be
a possibility to deprecate API for removal if the Community decided to
do so.

I can totally imagine a scenario where a large Ignite user surfaces with

it will graduate to beta some time in future.

I see no difficulty in assinging each cancellable object an IgniteUuid
(which is actually java UUID and is guaranteed to be unique per node).
We can have registry of running queries and just poking to what registry is
enough to understand query type.

Vladimir,
IGNITE_REUSE_MEMORY_ON_DEACTIVATE doesn't prevent cache contents from
clearing.
It allows allocated memory reuse on re-activation to avoid OS specific
issues if allocated heap is rather large.
You are right to create separate ticket for implementing required behavior.
