Kirill Tkalenko updated IGNITE-23115:
-------------------------------------
Description:
As far as I know, writing multiple files from multiple threads is more
efficient that writing a single file from multiple threads. But that's exactly
what we do.
We should make an alternative implementation that would distribute partitions
between threads and check if it performs better than current implementation.
The POC showed that writing dirty pages of a partition by one thread is more
efficient than by several threads concurrently.
PR: [ignite-3/pull/4366|https://github.com/apache/ignite-3/pull/4366].
Test: *org.apache.ignite.internal.storage.pagememory.mv.CpWritePagesTest*.
Logs: .
Results:
Total - needs to be implemented.
