Sahil Takiar created IMPALA-8826: ------------------------------------ Summary: Impala Doc: Add docs for PLAN_ROOT_SINK Key: IMPALA-8826 URL: https://issues.apache.org/jira/browse/IMPALA-8826 Project: IMPALA Issue Type: Sub-task Components: Docs Reporter: Sahil Takiar
Currently, I don't see many docs explaining what a {{PLAN_ROOT_SINK}} is, even though it shows up in explain plans and runtime profiles. After more of the changes inĀ IMPALA-8656 are merged, understanding what {{PLAN_ROOT_SINK}} is will be more important, because it will start taking up a memory reservation and possibly spilling to disk. I don't see any docs on data sinks in general, so perhaps it would be useful to create a dedicated page for explaining data sinks and how they work. We can start by documenting the {{PLAN_ROOT_SINK}} as that may be the most commonly used one. -- This message was sent by Atlassian JIRA (v7.6.14#76016) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-all-unsubscr...@impala.apache.org For additional commands, e-mail: issues-all-h...@impala.apache.org
