Dinesh Garg reassigned IMPALA-8632: ----------------------------------- Assignee: Xiaomeng Zhang (was: Vihang Karajgaonkar) > Add support for self-event detection for insert events > ------------------------------------------------------ > > Key: IMPALA-8632 > URL: https://issues.apache.org/jira/browse/IMPALA-8632 > Project: IMPALA > Issue Type: Sub-task > Reporter: Vihang Karajgaonkar > Assignee: Xiaomeng Zhang > Priority: Critical > > In case of {{INSERT_EVENTS}} if Impala inserts into a table it causes a > refresh to the underlying table/partition. This could be unnecessary when > there is only one Impala cluster in the system. The existing self-event > detection framework cannot identify such events because they are not sending > HMS objects like tables and partitions to the HMS. Instead in case of > {{INSERT_EVENT}} HMS API only asks for a table name or partition value to > fire a insert event on it. > We can detect a self-event in such cases if the HMS API to fire a listener > event is improved to return the event id. This would be used by > EventProcessor to ignore the event when it is fetched later in the next > polling cycle. In order to support this, we will need to make a change to > Hive as well so that the enhanced API can be used. -- 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
