Ryan King commented on CASSANDRA-1983: -------------------------------------- Alternatively, since we'll need a host->uuid mapping for counters we can put that uuid in the filename along with a serial integer (make it a long and we should be ok, right?) > Make sstable filenames contain a UUID instead of increasing integer > ------------------------------------------------------------------- > > Key: CASSANDRA-1983 > URL: https://issues.apache.org/jira/browse/CASSANDRA-1983 > Project: Cassandra > Issue Type: Improvement > Components: Core > Affects Versions: 0.7.0 > Reporter: David King > Priority: Minor > > sstable filenames look like CFName-1569-Index.db, containing an integer for > uniqueness. This makes it possible (however unlikely) that the integer could > overflow, which could be a problem. It also makes it difficult to collapse > multiple nodes into a single one with rsync. I do this occasionally for > testing: I'll copy our 20 node cluster into only 3 nodes by copying all of > the data files and running cleanup; at present this requires a manual step of > uniqifying the overlapping sstable names. If instead of an incrementing > integer, it would be handy if these contained a UUID or somesuch that > guarantees uniqueness across the cluster. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
