    Description

      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.
