Jonathan Ellis updated CASSANDRA-4694:
--------------------------------------
Reviewer: brandon.williams
Priority: Minor (was: Critical)
Affects Version/s: (was: 1.1.5)
Fix Version/s: 1.1.6
Assignee: Alexey Zotov
the description about "need to fit in memory only one of them" makes me wonder
if we're on the same page about what this option does, but i'm open to making
it finer-grained.
tagged fix-for 1.1.6 but open to reserving for 1.2 if it looks dicey at all.
> populate_io_cache_on_flush option should be configurable for each column
> family independently

> I suggest to configure populate_io_cache_on_flush option for each column
> family. It should be configurable from cassandra-cli and should be stored in
> System keyspace.
> That could be useful if you have a few column families inside single keyspace
> and you need to fit in memory only one of them.
> Patch has been attached. I've been testing it on pseudo-cluster using ccm. So
> I don't have fully confidence about lack of bugs. Please carefully review
> that code.
