---------------------------------
Summary: Increase the default of raft.server.log.segment.size.max
Key: RATIS-1924
URL: https://issues.apache.org/jira/browse/RATIS-1924
Project: Ratis
Issue Type: Improvement
Components: server
Reporter: Tsz-wo Sze
Assignee: Tsz-wo Sze
Currently, the default is 8MB which is very small. The servers will roll the
log frequently and create a lot of small files.
According to [~William Song]'s
[comment|https://github.com/apache/ratis/pull/953#discussion_r1376972528], 32MB
seems a good choice.

It's only that I did experiments earlier and found 32MB is the optimal for
IOTDB default workload. The experiments show:
- (end to end throughput) improves substantially as segmented size grow from
8MB to 32MB, slowly from 32MB to 128MB.
- The memory usage in JVM young increases as the segmented size grow, even if
we restricted the max-cached-size and max-cached-segments. It turned out to be
the open segment.
