hi, all I use YCSB to measure the insert/read latency of hbase. I found there will be 0 records inserted in up to 10 seconds during the insertion procedure. See the following result at 1514 second. I want to know why this occurs. Is this due to compaction? And I also want to know why the ops/sec varies all the time. Seems no a stable time. Thanks.
