[jira] [Created] (CASSANDRA-15261) Improve performance by adding
serialize cache in mutation
Shen dayu created CASSANDRA-15261:
-------------------------------------
Summary: Improve performance by adding serialize cache in mutation
Key: CASSANDRA-15261
URL: https://issues.apache.org/jira/browse/CASSANDRA-15261
Project: Cassandra
Issue Type: Improvement
Components: Consistency/Batch Log
Reporter: Shen dayu
I am trying to add a serialize cache in mutation, for there is so many redundant serialization
# calculate binary size before serialize to binary, this calculation double the serialization operation.
# reuse binary in network message for commitlog, this can reduce a serialization operation
In my test, I use cassandra version is 3.0.14, and it gains 20% performance improvement.
I know cassandra 3.0.x only accept critical bug fixes now.
So I was wondering any one would review my code if I patch this for 4.0
