Hi Andrew, Thanks for the idea. However, there is no real timing here. I have a MR building this table, and each time I re-launch the MR, I need to clean the table first. But I reallt would like to keep the way HBased splitted it instead of having to do manual splits, or starting with one region.
So I will wait for Kevin to complete https://issues.apache.org/jira/browse/HBASE-5525 ;) JM 2013/2/5, Andrew Purtell <[email protected]>: > If there is a time consideration here, perhaps you want to do this because > the data isn't interesting after some time interval has elapsed but the > keyspace for new entries will be similar -- then consider using TTLs.
