Fabian Hueske commented on FLINK-5859: -------------------------------------- Hi [~godfreyhe] and [~ykt836], sounds good to me. +1 to revisit this approach if we figure out that it restricts us in some way or leads to sub-optimal plans. > support partition pruning on Table API & SQL > -------------------------------------------- > > Key: FLINK-5859 > URL: https://issues.apache.org/jira/browse/FLINK-5859 > Project: Flink > Issue Type: New Feature > Components: Table API & SQL > Reporter: godfrey he > Assignee: godfrey he > > Many data sources are partitionable storage, e.g. HDFS, Druid. And many > queries just need to read a small subset of the total data. We can use > partition information to prune or skip over files irrelevant to the user’s > queries. Both query optimization time and execution time can be reduced > obviously, especially for a large partitioned table. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
