Niels Basjes created HBASE-11990: ------------------------------------ Summary: Make setting the start and stop row for a specific prefix easier Key: HBASE-11990 URL: https://issues.apache.org/jira/browse/HBASE-11990 Project: HBase Issue Type: New Feature Components: Client Reporter: Niels Basjes
If you want to set a scan from your application to scan for a specific row prefix this is actually quite hard. As described in several places you can set the startRow to the prefix; yet the stopRow should be set to the prefix '+1' If the prefix 'ASCII' put into a byte[] then this is easy because you can simply increment the last byte of the array. But if your application uses real binary rowids you may run into the scenario that your prefix is something like { 0x12, 0x23, 0xFF, 0xFF }. Then the increment should be { 0x12, 0x24, 0x00, 0x00 }. I have prepared a proposed patch that makes setting these values correctly a lot easier. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
