- Default is 10000000. The maximum number of records allowed to be
broadcast as part of a join. After one million records, Drill reshuffles data
rather than doing a broadcast to one side of the join. To improve performance
you can increase this number, especially on 10GB Ethernet clusters.

- Drill uses a native reader to read Hive tables when you enable the

option]({{site.baseurl}}/docs/configuration-options-introduction/). When
enabled, Drill reads data faster and applies filter pushdown optimizations.
