Anubhav Kale created CASSANDRA-11160: ----------------------------------------
Summary: Use UUID for SS Table Filenames Key: CASSANDRA-11160 URL: https://issues.apache.org/jira/browse/CASSANDRA-11160 Project: Cassandra Issue Type: Improvement Reporter: Anubhav Kale Priority: Minor Today, Cassandra uses monotonically increasing counter to generate SS Table file names. While this works practically, wouldn't it be safer / better if UUIDs are used in file names to make them really unique ? AFAIK, no code paths rely on such counters being part of files. A specific scenario where this will really help is below: In backup / restore model, suppose we move files out to some other storage. In that process, we can optimize by not moving files that were already backed up using a check on file names (which we can't do easily today because if the node went down, a file with same name can be generated). Note that using incremental backups is not a viable option here, because we lose the benefits of compaction (as discussed in my last comment of CASSANDRA-10960). -- This message was sent by Atlassian JIRA (v6.3.4#6332)
