> Currently ratis segment size is set to 1GB. After RATIS-253, the entry size
> for a write Chunk is not counted towards the entry being written to Raft Log.
> This jira controls the segment size to 16KB which makes sure that the number
> of entries with WriteChunk is limited to 64. This means with 16MB chunk, the
> total data pending in the segment is 1GB.
