Subject [jira] [Commented] (CASSANDRA-14118) Refactor write path
Date Sat, 17 Mar 2018 00:26:00 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-14118?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16403152#comment-16403152

Dikang Gu commented on CASSANDRA-14118:
---------------------------------------

Hmm, I'm not sure what else you want me to abstract. As I mentioned, on the local code path,
Keyspace.applyInternal -> cfs.apply() -> writehandler.apply(), there are no memtable
and sstable involved already. Only component is the commitlog, which I pass it as the parameter
in the apply() function already.

> As part of the pluggable storage engine effort, we'd like to modularize the write path
related code, make it to be independent from existing storage engine implementation details.
> For now, refer to https://docs.google.com/document/d/1suZlvhzgB6NIyBNpM9nxoHxz_Ri7qAm-UEO8v8AIFsc
for high level designs.
