Jonathan Ellis commented on CASSANDRA-6356:
-------------------------------------------
Could we move the DIGEST component into ValidationMetadata?
Should we add a "table of contents" to the serialized metadata so we can seek
to a given sub-component w/o having to scan everything?
> Proposal: Statistics.db (SSTableMetadata) format change

> URL: https://issues.apache.org/jira/browse/CASSANDRA-6356
> Project: Cassandra
> Issue Type: Improvement
> Reporter: 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.
