Vijay updated CASSANDRA-2392: ----------------------------- Attachment: 0001-CASSANDRA-2392-V7.patch Rebased, the changes/breaks CASSANDRA-4023 but it is fine because the cost is during the upgrade and not seen after that (The cost of deserialization dk for index summary). I am going to work on 3762, I think we can commit it independently now. > 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-V7.patch, > 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.

Our indexes are quite large. -- This message is automatically generated by JIRA.
