bersprockets edited a comment on issue #23392: [SPARK-26450][SQL] Avoid rebuilding map of schema for every column in projection URL: https://github.com/apache/spark/pull/23392#issuecomment-451701800 Note: There are two remaining places that use the pattern: ```scala collectionLikeThing.map(x => BindReferences.bindReference(x, list)) ``` Those places are HiveTableScanExec (```boundPruningPred```) and InMemoryTableScanExec (```partitionFilters```). However, both are those are actually iterating over an Option rather than a collection of multiple items. So I left them as-is.
