[jira] [Created] (CASSANDRA-6356) Proposal: Statistics.db (SSTableMetadata) format change

Yuki Morishita created CASSANDRA-6356:
-----------------------------------------

             Summary: Proposal: Statistics.db (SSTableMetadata) format change
                 Key: CASSANDRA-6356
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-6356
             Project: Cassandra
          Issue Type: Improvement
            Reporter: Yuki Morishita
            Assignee: Yuki Morishita
            Priority: Minor
             Fix For: 2.1


We started to distinguish what's loaded to heap, and what's not from Statistics.db. For now, ancestors are loaded as they needed.

Current serialization format is so adhoc that adding new metadata that are not permanently hold onto memory is somewhat difficult and messy. I propose to change serialization format so that a group of stats can be loaded as needed.
