Vladimir Rodionov commented on HBASE-15539:
-------------------------------------------
I load 1B small rows (rowkey=16 byte, value = 8 bytes) using BufferedMutator
with batch size 1000. Table has 1 CF, only one region, splits are disabled.
Compaction is on, but maximum selection size is limited to 1GB. Test runs
locally on my laptop (MBP, fast SSD).
> HBase Client region location is expensive
