Hello everyone, I have a two node hbase cluster with each node running a data-node and a region-server. I am running YCSB benchmark on this cluster. I have these two counter-intuitive following interesting observation which I could not explain. Hoping someone could help understand these behavior.
Experiment 1: a) Write Only - 100% insert workload vs b) Write heavy - 90 % insert and 10% read Observation: While average insert latency for write heavy is around 15 us, the average insert latency is about 70x to 120x more for Write only operations Experiment 2: c) Write only workload with default compaction scheme, vs d) Write only workload with major and minor compaction off Observation: While less data is written for compaction off, the insert latency is lesser for default setting. Thanks for any help. Abhishek -- View this message in context: http://apache-hbase.679495.n3.nabble.com/insert-latency-tp4061748.html Sent from the HBase User mailing list archive at Nabble.com.
