Francisco Guerrero updated CASSANDRA-18697: ------------------------------------------- Test and Documentation Plan: No tests added Status: Patch Available (was: In Progress) CI: [https://app.circleci.com/pipelines/github/frankgh/cassandra/124/workflows/5f9bd478-41d2-43dc-988a-cb2bb0199560] > Skip ColumnFamilyStore#topPartitions initialization when client or tool mode > ---------------------------------------------------------------------------- > > Key: CASSANDRA-18697 > URL: https://issues.apache.org/jira/browse/CASSANDRA-18697 > Project: Cassandra > Issue Type: Bug > Components: Tool/bulk load > Reporter: Francisco Guerrero > Assignee: Francisco Guerrero > Priority: Normal > Time Spent: 10m > Remaining Estimate: 0h > > In {{org.apache.cassandra.db.ColumnFamilyStore}} the {{topPartitions}} is > initialized when the keyspace is not a system keyspace. However, when running > the cassandra library as client mode or tool mode, the initialization also > happens. However, {{TopPartitionTracker}} performs queries to the {{system}} > keyspace, which might not be available in most of the cases. For that reason, > we should skip initialization of {{topPartitions}} when running on client > mode or tool mode. > In utilities and external libraries, this can produce a warning that is > displayed with a stack trace. This warning can be misleading for end users, > and can cause confusion. But more importantly, the initialization of > {{topPartitions}} is not required in this mode. > The warning is similar to this: > {code:java} > WARN org.apache.cassandra.db.SystemKeyspace: Could not load stored top > SIZES partitions for ... > org.apache.cassandra.db.KeyspaceNotDefinedException: keyspace system does > not exist > at > org.apache.cassandra.schema.Schema.validateTable(Schema.java:xxx) ~[?:?] > at > org.apache.cassandra.cql3.statements.SelectStatement$RawStatement.prepare(SelectStatement.java:xxx) > ~[?:?] > at > org.apache.cassandra.cql3.statements.SelectStatement$RawStatement.prepare(SelectStatement.java:xxx) > ~[?:?] > at > org.apache.cassandra.cql3.statements.SelectStatement$RawStatement.prepare(SelectStatement.java:xxx) > ~[?:?] > at > org.apache.cassandra.cql3.QueryProcessor.parseAndPrepare(QueryProcessor.java:xxx) > ~[?:?] > ... {code} -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
