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
