Subject Re: 3k sstables during a repair incremental !!
Date Wed, 10 Feb 2016 13:34:51 GMT
Correction:
*table cf3*
*        Space used (live): 697.03 MB*

It happens that when I do repair -inc -par on theses tables, *cf3 got a
pick of 3k sstables*. When the repair finish, it takes 30 min or more to
finish all the compactations and return to 6 sstable.



Saludos
