Aleksey Yeschenko updated CASSANDRA-8586:
-----------------------------------------
Assignee: (was: Aleksey Yeschenko)
> support millions of sstables by lazily acquiring/caching/dropping filehandles
> -----------------------------------------------------------------------------
>
> Key: CASSANDRA-8586
> URL: https://issues.apache.org/jira/browse/CASSANDRA-8586
> Project: Cassandra
> Issue Type: New Feature
> Reporter: Tupshin Harper
> Labels: dense-storage
> Fix For: 3.x
>
>
> This might turn into a meta ticket if other obstacles are found in the goal
> of supporting a huge number of sstables.
> Technically, the only gap that I know of to prevent us from supporting absurd
> numbers of sstables is the fact that we hold on to an open filehandle for
> every single sstable.
> For use cases that are willing to take a hit to read-performance in order to
> achieve high densities and low write amplification, a mechanism for only
> retaining file handles for recently read sstables could be very valuable.
> This will allow for alternate compaction strategies and compaction strategy
> tuning that don't try to optimize for read performance as aggresively.
