> Key: IGNITE-21798
> URL: https://issues.apache.org/jira/browse/IGNITE-21798
> Project: Ignite
> Issue Type: Improvement
> Reporter: Vladislav Pyatkov
> Priority: Major
> Labels: ignite-3
>
> h3. Motivation
> We always have to work to reduce the number of threads in the product. In
> this case, we create a double CPU for each disruptor that is used in the
> replication layer. This is a lot of threads, and it is redundant in most
> cases. We have to create a property to regulate the number in a specific case.
> h3. Implementation notes
> * The default number of threads should stay the same until we don't have a
> test that shows a more stable value.
> * IGNITE_RAFT_STRIPES is a system property to configure the number of stripes.
> * IGNITE_RAFT_WAL_STRIPES is a system property to configure the number of
> threads that are used to write WAL.
> * IGNITE_RAFT_WAL_YIELD_STRATEGY is a system property to use the Yield
> strategy for WAL writer threads.
> h3. Definition of done
> Prepare all the described system properties
> The task also assumes a throughput test scenario description
