Liu Shaohui commented on HBASE-9543: ------------------------------------ Thanks for review. [~yuzhih...@gmail.com]. a, What's your suggestion about the method name? getUniqueValues? b, I may change the IoException to ExecutionException. Once the client receives ExecutionException from regionserver, the method will turn immediately. But the requests that have been send can not been canceled. c, For partial results, i think it's not acceptable. We may add more comments about limitation of the method. > Impl unique aggregation > ------------------------ > > Key: HBASE-9543 > URL: https://issues.apache.org/jira/browse/HBASE-9543 > Project: HBase > Issue Type: New Feature > Components: Coprocessors > Reporter: Liu Shaohui > Assignee: Liu Shaohui > Priority: Minor > Attachments: HBASE-9543-0.94-v1.diff, HBASE-9543-trunk-v1.diff, > HBASE-9543-trunk-v2.diff, HBASE-9543-trunk-v3.diff, HBASE-9543-trunk-v4.diff > > > Impl unique aggregation: return a set of all columns' values in a scan. -- This message was sent by Atlassian JIRA (v6.1#6144)
