Subject Re: Flushs and compactions
Date Wed, 05 Aug 2015 17:25:47 GMT
I tried that with 1.0.1 but I think it's the same with 1.1.0.

How to reproduce:

create 'testflush', 'f1'
put 'testflush', 'row1', 'f1:c1', 'val1'
flush 'testflush'
put 'testflush', 'row1', 'f1:c1', 'val1'
flush 'testflush'
put 'testflush', 'row1', 'f1:c1', 'val1'
flush 'testflush'
put 'testflush', 'row1', 'f1:c1', 'val1'
flush 'testflush'
put 'testflush', 'row1', 'f1:c1', 'val1'
flush 'testflush'
put 'testflush', 'row1', 'f1:c1', 'val1'
flush 'testflush'
put 'testflush', 'row1', 'f1:c1', 'val1'
flush 'testflush'
put 'testflush', 'row1', 'f1:c1', 'val1'
flush 'testflush'
put 'testflush', 'row1', 'f1:c1', 'val1'
flush 'testflush'
put 'testflush', 'row1', 'f1:c1', 'val1'
flush 'testflush'
put 'testflush', 'row1', 'f1:c1', 'val1'
flush 'testflush'

Result:

I can test the same on 1.1.0 if you want, just let me know.
