Jacques Nadeau updated DRILL-3333: ---------------------------------- Fix Version/s: 1.1.0 > Add support for auto-partitioning in parquet writer > --------------------------------------------------- > > Key: DRILL-3333 > URL: https://issues.apache.org/jira/browse/DRILL-3333 > Project: Apache Drill > Issue Type: Bug > Reporter: Steven Phillips > Assignee: Steven Phillips > Fix For: 1.1.0 > > Attachments: DRILL-3333.patch, DRILL-3333.patch, > DRILL-3333_2015-06-22_15:22:11.patch, DRILL-3333_2015-06-23_17:38:32.patch, > DRILL-3333_tests.patch > > > When a table is created with a partition by clause, the parquet writer will > create separate files for the different partition values. The data will first > be sorted by the partition keys, and the parquet writer will create new file > when it encounters a new value for the partition columns. > When data is queried against the data that was created this way, partition > pruning will work if the filter contains a partition column. And unlike > directory based partitioning, no view is required, nor is it necessary to > reference the dir* column names. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
