Thanks for reviewing Duo. Yes, the setStartStopRowForPrefixScan method works for prefix filtering, but it can not work for range filtering. Maybe the title misunderstood you. What I want to introduce here, is like the query optimizer sub-system in RSBMS. It will optimize the scan range based on the filters that user sets. For example, if user want to scan data where rowkey > 'hhh' and rowkey < 'mmm', the optimizer can optimize start row to 'hhh' and stop row to 'mmm'. Compare to the default start row and stop row, EMPTY_START_ROW and EMPTY_STOP_ROW, this will help speed up scan request. -- This is an automated message from the Apache Git Service.
