Ben Kietzman created ARROW-7051: ----------------------------------- Summary: [C++] Improve MakeArrayOfNull to support creation of multiple arrays Key: ARROW-7051 URL: https://issues.apache.org/jira/browse/ARROW-7051 Project: Apache Arrow Issue Type: Improvement Components: C++ Affects Versions: 0.14.0 Reporter: Ben Kietzman Assignee: Ben Kietzman Fix For: 1.0.0
MakeArrayOfNull reuses a single buffer of {{0}} for all buffers in the array it creates. It could be extended to reuse that same buffer for all buffers in multiple arrays. This optimization will make RecordBatchProjector and ConcatenateTablesWithPromotion more memory efficient -- This message was sent by Atlassian Jira (v8.3.4#803005)
