> ------------------------------------------------------------------------
>
> Key: CASSANDRA-8584
> URL: https://issues.apache.org/jira/browse/CASSANDRA-8584
> Project: Cassandra
> Issue Type: Improvement
> Components: Local Write-Read Paths, Observability
> Reporter: Joshua McKenzie
> Assignee: Ariel Weisberg
> Priority: Trivial
> Fix For: 3.0 alpha 1
>
> Attachments: 8584_v1.txt, NoSpamLogger.java, nospamlogger.txt
>
>
> Since trySkipCache returns an errno rather than -1 and setting errno like our
> other CLibrary calls, it's thread-safe and we could print out more helpful
> information if we failed to prompt the kernel to skip the page cache. That
> system call should always succeed unless we have an invalid fd as it's free
> to ignore us.
> Commit log lag is already rate limited by its own implementation. Convert to
> use NoSpamLogger.
