Subject [jira] [Commented] (CASSANDRA-2475) Prepared statements
Date Thu, 15 Dec 2011 04:07:30 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-2475?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13169957#comment-13169957

Jonathan Ellis commented on CASSANDRA-2475:
-------------------------------------------

bq. To clarify, you're saying you're in favor of putting no constraints whatsoever on the
number of stored statements, and relying solely on clients to free them up?

That's what I meant, yes.

bq. Does this change at all (the perceived likelihood) if the number were 1,000 instead of
51? Or 10,000?

If a client is doing it "right," then it will use pooled connections, each of which will use
PS for each query needed by the app.  Hundreds or even thousands isn't crazy.  So I'd be okay
with a limit of 10000 as "practically equivalent to unlimited for all intents and purposes,
but it might save you from a buggy client."
