Bikramjeet Vig resolved IMPALA-7351. ------------------------------------ Fix Version/s: Impala 3.4.0 Resolution: Fixed > Add memory estimates for plan nodes and sinks with missing estimates > -------------------------------------------------------------------- > > Key: IMPALA-7351 > URL: https://issues.apache.org/jira/browse/IMPALA-7351 > Project: IMPALA > Issue Type: Sub-task > Components: Frontend > Reporter: Tim Armstrong > Assignee: Bikramjeet Vig > Priority: Major > Labels: admission-control, resource-management > Fix For: Impala 3.4.0 > > > Many plan nodes and sinks, e.g. KuduScanNode, KuduTableSink, ExchangeNode, > etc are missing memory estimates entirely. > We should add a basic estimate for all these cases based on experiments and > data from real workloads. In some cases 0 may be the right estimate (e.g. for > streaming nodes like SelectNode that just pass through data) but we should > remove TODOs and document the reasoning in those cases. -- This message was sent by Atlassian Jira (v8.3.2#803003) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-all-unsubscr...@impala.apache.org For additional commands, e-mail: issues-all-h...@impala.apache.org
