Subject [jira] [Commented] (CASSANDRA-3773) make default schema migration wait time RING_DELAY
Date Mon, 23 Jan 2012 20:43:43 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-3773?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13191433#comment-13191433

Jonathan Ellis commented on CASSANDRA-3773:
-------------------------------------------

The real problem is that if you're pushing schema changes and have to wait for a compaction,
even RING_DELAY or longer probably won't be enough.  CASSANDRA-3116 addresses this for 1.1.

> The default of 10 seconds feels strange to me since we have established that RING_DELAY
is the appropriate wait time for gossip, which should include schema migrations.
> Patch makes it RING_DELAY by default. Alternate patch makes it 30 seconds; I don't know
how much we care about not referencing non-CLI code from the CLI.
