HBase1.0 API Problem: setAutoFlush and flushCommits

Hi, experts.


I migrated my HBase cluster from version 0.98.10 to version 1.0. I find that in HBase1.0 the class "Table" does not contain the API setAutoFlush and flushCommits any more. Could anybody tell me where these APIs go? What should I do now if I want to make a commitment after some Puts operations?


Many Thanks!

Yes, although the new Table interface implementation (it really is a HUMBLE but now hidden from you and might change in the future) is using a BufferedMutator internally, it will flush at the end of every operation.
