John Carrino commented on HBASE-4811: ------------------------------------- A common workflow for me would to be to do a forward/reverse index lookup. Basically find the first row that is after/before a given key. I think for this case both forward and reverse index lookups would be approximately the same speed. > Support reverse Scan > -------------------- > > Key: HBASE-4811 > URL: https://issues.apache.org/jira/browse/HBASE-4811 > Project: HBase > Issue Type: Improvement > Components: Client > Affects Versions: 0.20.6 > Reporter: John Carrino > > All the documentation I find about HBase says that if you want forward and > reverse scans you should just build 2 tables and one be ascending and one > descending. Is there a fundamental reason that HBase only supports forward > Scan? It seems like a lot of extra space overhead and coding overhead (to > keep them in sync) to support 2 tables. > I am assuming this has been discussed before, but I can't find the > discussions anywhere about it or why it would be infeasible. -- This message is automatically generated by JIRA.
