Andy Grove created ARROW-9838: --------------------------------- Summary: [Rust] [DataFusion] Physical planner should insert explicit MergeExec nodes Key: ARROW-9838 URL: https://issues.apache.org/jira/browse/ARROW-9838 Project: Apache Arrow Issue Type: Sub-task Components: Rust, Rust - DataFusion Reporter: Andy Grove Assignee: Andy Grove Fix For: 2.0.0
Operators such as GlobalLimitExec, SortExec, and HashAggregateExec (in some cases) require a single input partition. Rather than have these operators perform their own merging of input partitions, the planner should insert explicit MergeExec nodes into the physical plan, when needed. -- This message was sent by Atlassian Jira (v8.3.4#803005)
