Andrew Lamb created ARROW-10165: ----------------------------------- Summary: [Rust] [DataFusion] Add DictionaryArray coercion support Key: ARROW-10165 URL: https://issues.apache.org/jira/browse/ARROW-10165 Project: Apache Arrow Issue Type: Sub-task Reporter: Andrew Lamb Assignee: Andrew Lamb
There is code in the datafusion physical planner that coerces arguments to compatible types for some expressions (e.g. for equals: https://github.com/apache/arrow/blob/master/rust/datafusion/src/physical_plan/expressions.rs#L1153) This code needs to be modified to understand dictionary types (so, for example we can express a predicate like {{col1 = "foo"}}, where {{col1}} is a DictionaryArray. -- This message was sent by Atlassian Jira (v8.3.4#803005)
