Jonathan Ellis commented on CASSANDRA-2392: ------------------------------------------- For the record, I'm still fine with saying "loading caches will slow down startup, deal with it," but I think we have a good plan of attack on 3762 now and it may be simpler to just do that first, before rebasing this. Which is also fine. > Saving IndexSummaries to disk > ----------------------------- > > Key: CASSANDRA-2392 > URL: https://issues.apache.org/jira/browse/CASSANDRA-2392 > Project: Cassandra > Issue Type: Improvement > Reporter: Chris Goffinet > Assignee: Vijay > Priority: Minor > Fix For: 1.2 > > Attachments: 0001-CASSANDRA-2392-v6.patch, > 0001-re-factor-first-and-last.patch, 0001-save-summaries-to-disk-v4.patch, > 0001-save-summaries-to-disk.patch, 0002-save-summaries-to-disk-v2.patch, > 0002-save-summaries-to-disk-v3.patch, 0002-save-summaries-to-disk.patch, > CASSANDRA-2392-v5.patch > > > For nodes with millions of keys, doing rolling restarts that take over 10 > minutes per node can be painful if you have 100 node cluster. All of our time > is spent on doing index summary computations on startup. It would be great if > we could save those to disk as well. Our indexes are quite large. -- This message is automatically generated by JIRA.
