Jonathan Ellis commented on CASSANDRA-3206:
-------------------------------------------
Jeremy pointed out that we can also use a large number of FDs during
compaction: either major compaction for tiered strategy, or a L0 compaction
under Leveled, can open an effectively arbitrary number of sstables if
compaction is behind.
> increase file descriptor limit in deb, rpm packages

> URL: https://issues.apache.org/jira/browse/CASSANDRA-3206
> Project: Cassandra
> Issue Type: Bug
> Components: Packaging
> Reporter: Jonathan Ellis
> Assignee: paul cannon
> Priority: Minor
> Fix For: 0.8.6
>
>
> We can use a lot of file descriptors (one per socket, 5? per sstable).
> People hit this regularly on the user list and it will get worse with Leveled
> compaction, which limits sstable size to a relatively low size (currently
> 5MB).
