Subject [jira] [Updated] (CASSANDRA-8671) Give compaction strategy more control over where sstables are created, including for flushing and streaming.
Date Fri, 14 Aug 2015 13:34:46 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-8671?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Blake Eggleston updated CASSANDRA-8671:
---------------------------------------
    Attachment: 8671-giving-compaction-strategies-more-control-over.txt

patch against cassandra-3.0 attached. This provides an interface for both an sstablewriter
wrapper for flush and stream, as well as a compaction aware writer interface. It also optionally
lets compaction strategies use additional directories.

> This would enable routing different partitions to different disks based on some user
defined parameters.
> My initial take on how to do this would be to make an interface from SSTableWriter, and
have a table's compaction strategy do all SSTableWriter instantiation. Compaction strategies
could then implement their own SSTableWriter implementations (which basically wrap one or
more normal sstablewriters) for compaction, flushing, and streaming.
