> Convert Excel Reader to Use Streaming Reader
> --------------------------------------------
>
> Key: DRILL-7641
> URL: https://issues.apache.org/jira/browse/DRILL-7641
> Project: Apache Drill
> Issue Type: Improvement
> Components: Storage - Text & CSV
> Affects Versions: 1.17.0
> Reporter: Charles Givre
> Assignee: Charles Givre
> Priority: Major
> Fix For: 1.18.0
>
>
> The current implementation of the Excel reader uses the Apache POI reader,
> which uses excessive amounts of memory. As a result, attempting to read large
> Excel files will cause out of memory errors.
> This PR converts the format plugin to use a streaming reader, based still on
> the POI library. The documentation for the streaming reader can be found
> here. [1]
> All unit tests pass and I tested the plugin with some large Excel files on my
> computer.
