Tim Armstrong created IMPALA-9274: ------------------------------------- Summary: Implement phased barrier synchronisation construct Key: IMPALA-9274 URL: https://issues.apache.org/jira/browse/IMPALA-9274 Project: IMPALA Issue Type: Sub-task Reporter: Tim Armstrong
We need a synchronisation primitive that allows n threads to synchronise by joining on a barrier, then having the last arriving thread execute some code and then wake up all of the other threads. This is required for implementing phases of the hash join algorithm. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-all-unsubscr...@impala.apache.org For additional commands, e-mail: issues-all-h...@impala.apache.org
