Qifan Chen has uploaded a new patch set (#2). ( http://gerrit.cloudera.org:8080/17568 )
Change subject: IMPALA-10738: Min/max filters should be enabled for partition columns ...................................................................... IMPALA-10738: Min/max filters should be enabled for partition columns This patch enables min/max filters for partitoned columns to take advantage of the min/max filter infrastructure already built. To turn on the feature, set query option minmax_filter_threshold to a value greater than 0. In the patch, the existing query option enabled_runtime_filter_types is made to play a role in the types of the filters generated. The default value ALL generates both the bloom and min/max filters. The alternative value BLOOM generates only the bloom filters and another alternative value MIN_MAX generates only the min/max filters. Testing: 1). Added a new test in overlap_min_max_filters.test to verify that a min/max filter is generated for a partition column and is able to filter out all partitions. 2).
