Date Tue, 11 Feb 2020 14:19:43 GMT
Igniters,


Current the 2.8 release status


1. The PR with RELEASE_NOTES fully updated [1].

2. Previously mentioned performance drop has not been confirmed. Run
many times in different environments. All test results within the
margin of error.
In-memory, putAll, 4 nodes, 1 client
IgnitePutAllBenchmark: +1%
IgnitePutAllTxBenchmark: -6%

3. Waiting for the vote completion
(Allow or prohibit a joint use of @deprecated and @IgniteExperimental)

4. Mark MVCC with IgniteExperimental [2].

5. Wait for ML examples to be fixed [3].
