Sergey Shelukhin commented on HBASE-7679:
-----------------------------------------

Yes, I did some testing with real random reads for HBaseCon slides, with yet-unpublished patch
about L0.
Latest round (8 writer threads, 3 updater threads, 1 deleter thread deleting no more than
5% of data, some verifiers and 8 random read threads):
{code}
Stripes (12) test starting on 3 servers; preloading 0 to 12000000 and writing to 30000000;
Failed to write keys: 0
Stripes (12) preload took 7776sec; sleeping for 30sec for store to stabilize
Failed to write keys: 0
Writers stopped for test Stripes (12)
Readers stopped for test Stripes (12)
Stripes (12) test took 12700sec
Default test starting on 3 servers; preloading 0 to 12000000 and writing to 30000000;

Default preload took 7956sec; sleeping for 30sec for store to stabilize
Failed to write keys: 0
