Edward Ribeiro updated CASSANDRA-8693: -------------------------------------- Summary: QueryProcessor.executeInternal(statement) never evictes statements from internal cache (was: QueryProcessor.executeInternal(statement) are never evicted from internal cache) > QueryProcessor.executeInternal(statement) never evictes statements from > internal cache > -------------------------------------------------------------------------------------- > > Key: CASSANDRA-8693 > URL: https://issues.apache.org/jira/browse/CASSANDRA-8693 > Project: Cassandra > Issue Type: Bug > Components: Core > Reporter: Edward Ribeiro > Labels: cql3 > Fix For: 2.1.2 > > Attachments: qp-internal.patch > > > QueryProcessor holds a reference to {{internalStatements}}, a map for > prepared statements used internally. > Those commands don't mix with the ones created by the user, but the problem > is that if a KS/CF is dropped and then recreated {{internalStatements}} > entries will point to invalid PreparedStatements (old cf_id) so any operation > on those statements will fail therefore. In fact, as of today, this map is > never actually cleaned no matter what. > This problem is similar to the ones addressed by > https://issues.apache.org/jira/browse/CASSANDRA-8652 and > https://issues.apache.org/jira/browse/CASSANDRA-7566, so those issues provide > any further context. > I am attaching a patch to this issue. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
