-----------------------------------------------
Component/s: Feature/Lightweight Transactions
> system.paxos performance improvements for LWT
> ---------------------------------------------
>
> Key: CASSANDRA-13548
> URL: https://issues.apache.org/jira/browse/CASSANDRA-13548
> Project: Cassandra
> Issue Type: Improvement
> Components: Feature/Lightweight Transactions, Legacy/Core
> Reporter: Jeff Jirsa
> Priority: Low
> Fix For: 4.x
>
>
> There are a few practical changes we can make to {{system.paxos}} that will
> improve (especially read) performance for LWT:
> - We should decrease the compression chunk size for situations where we have
> to go to disk
> - We can change the primary key structure so that the row key and CFID are
> both part of the partition key, which will decrease LCS compaction activity
> in use cases where a row key is common across tables, and one table is
> updated more frequently than the other.
