Liang-Chi Hsieh 4637fc08a3 [SPARK-11955][SQL] Mark optional fields in merging schema for safely pushdowning filters in Parquet ... JIRA: https://issues.apache.org/jira/browse/SPARK-11955 Currently we simply skip pushdowning filters in parquet if we enable schema merging. However, we can actually mark particular fields in merging schema for safely pushdowning filters in parquet. Author: Liang-Chi Hsieh <viirya@appier.com> Author: Liang-Chi Hsieh <viirya@gmail.com> Closes #9940 from viirya/safe-pushdown-parquet-filters.		2016-01-28 16:25:21 -08:00
