Re: disable major compaction per table
Thanks! does hbase compress repeated values in keys and columns :location say (ASIA). will that be repeated with each key or hbase snappy compression will handle that. same applies for repeated values of a column? Thanks!

Re: disable major compaction per table
bq. hbase.hregion.majorcompaction = 0 per table/column family I searched code base but didn't find relevant test case for the above. Mind giving me some pointer ?

Re: disable major compaction per table
1.does major compaction in hbase runs per table basis. Per Region 2.By default every 24 hours? In older versions - yes. Current (1.x+) - 7 days 3.Can I disable automatic major compaction for few tables while keep it enable for rest of tables? yes, you can. You can set hbase.hregion.majorcompaction = 0 per table/column family 4.Does hbase put ,get and delete are blocked while major compaction and are working in minor compaction? No, they are not. -Vlad On Tue, Feb 16, 2016 at 4:51 PM, Ted Yu wrote: > For #2, see http://hbase.apache.org/book.html#managed.compactions > > For #3, I don't think so. > > On Tue, Feb 16, 2016 at 4:46 PM, Shushant Arora > > wrote: > > > Hi > > > > 1.does major compaction in hbase runs per table basis. > > 2.By default every 24 hours? > > 3.Can I disable automatic major compaction for few tables while keep it > > enable for rest of tables? > > > > 4.Does hbase put ,get and delete are blocked while major compaction and > are > > working in minor compaction? > > > > Thanks > > >
Re: disable major compaction per table
For #2, see http://hbase.apache.org/book.html#managed.compactions For #3, I don't think so.

disable major compaction per table
Hi 1.does major compaction in hbase runs per table basis. 2.By default every 24 hours? 3.Can I disable automatic major compaction for few tables while keep it enable for rest of tables? 4.Does hbase put ,get and delete are blocked while major compaction and are working in minor compaction? Thanks
