> Key: CASSANDRA-396
> URL: https://issues.apache.org/jira/browse/CASSANDRA-396
> Project: Cassandra
> Issue Type: Improvement
> Components: Core
> Reporter: Jonathan Ellis
> Priority: Minor
>
> From a comment in CASSANDRA-213: it's a lot less IO (50% less reads, to be
> exact) to have anticompact split the old file into new files, each of which
> are served live until bootstrap is complete, at which point the sent file is
> removed, than to copy the to-send files out to a staging dir, and later
> re-scan the original file for cleanup & writing what is left. plus we get to
> remove the cleanup methods in ColumnFamilyStore, since they will be
> unnecessary.
> one other detail: we need to keep compaction from merging the to-send file
> until boostrap is complete.
