Date Wed, 31 May 2017 01:03:04 GMT


Jay Zhuang commented on CASSANDRA-13548:

How about making Paxos TTL configurable:
? Why it has to store at least 3 hours Paxos data?

> 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
> - 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.
