Jacek Lewandowski commented on CASSANDRA-17048: ----------------------------------------------- Done, one change from the previous comment - the last part is actually 18 chars long. I decided to encode nano part as separate 5 characters and random part as 13 characters for better readability - in this case the last 13 characters is not likely to change very often (just every restart of C* I suppose). OTOH when nano and random are combined they take 17 characters but the whole part is different for every generated ID. > Replace sequential sstable generation identifier with ULID > ---------------------------------------------------------- > > Key: CASSANDRA-17048 > URL: https://issues.apache.org/jira/browse/CASSANDRA-17048 > Project: Cassandra > Issue Type: Improvement > Components: Local/SSTable > Reporter: Jacek Lewandowski > Assignee: Jacek Lewandowski > Priority: Normal > Fix For: 4.1 > > Time Spent: 20m > Remaining Estimate: 0h > > Replace the current sequential sstable generation identifier with ULID based. > ULID is better because we do not need to scan the existing files to pick the > starting number as well as we can generate globally unique identifiers. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
