Alex Rodoni reassigned IMPALA-8826: ----------------------------------- Assignee: Alex Rodoni > Impala Doc: Add docs for PLAN_ROOT_SINK and result spooling > ----------------------------------------------------------- > > Key: IMPALA-8826 > URL: https://issues.apache.org/jira/browse/IMPALA-8826 > Project: IMPALA > Issue Type: Sub-task > Components: Docs > Reporter: Sahil Takiar > Assignee: Alex Rodoni > Priority: Major > Labels: future_release_doc > > 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. > We should document all the changes being made inĀ IMPALA-8656 as well. -- 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
