-------------------------------------------
Fix Version/s: 5.0
> Reduce size of per-SSTable index components
> -------------------------------------------
>
> Key: CASSANDRA-18673
> URL: https://issues.apache.org/jira/browse/CASSANDRA-18673
> Project: Cassandra
> Issue Type: Improvement
> Components: Feature/SAI
> Reporter: Mike Adamson
> Assignee: Mike Adamson
> Priority: Urgent
> Fix For: 5.0-alpha1, 5.0, 5.1
>
> Time Spent: 6.5h
> Remaining Estimate: 0h
>
> The current per-SSTable index components are large because the primary keys
> that are stored in them include the token as part of the byte comparable. The
> byte comparable puts the token first meaning that we get very little prefix
> compression from either the trie or the sorted terms store.
> We can fix this by removing the token from the primary key serialization.
> This would allow us to get the prefix compression from the trie and the
> sorted terms store.
