ASF GitHub Bot commented on FLINK-2168: --------------------------------------- Github user tonycox commented on the issue: https://github.com/apache/flink/pull/3149 @ramkrish86 ProjectableTableSource works in scan process. Without it TableScan is scanning all collumns and applying flatMap function on the whole data to project and filter. It's inefficient compared with pushing a projection and filtering right inside of scan proccess > Add HBaseTableSource > -------------------- > > Key: FLINK-2168 > URL: https://issues.apache.org/jira/browse/FLINK-2168 > Project: Flink > Issue Type: New Feature > Components: Table API & SQL > Affects Versions: 0.9 > Reporter: Fabian Hueske > Assignee: ramkrishna.s.vasudevan > Priority: Minor > > Add a {{HBaseTableSource}} to read data from a HBase table.
