Hello, hackers.
It might be a good idea to give users an opportunity to test their
applications with pgbench under different real-life-like load. So that
they will be able to see what's going to happen on production.
YCSB (Yahoo! Cloud Serving Benchmark) was taken as a concept. YCSB tests
were originally designed to facilitate performance comparisons of
different cloud data serving systems and it takes into account different
application workloads like:
workload A - assumes that application do a lot of reads(50%) and
updates(50%).
workload B - case when application do 95% of cases reads
and 5% updates
workload C - models behavior of read-only application.
workload E - the workload of the applications which in 95% of cases
requests for several neighboring tuples and in 5% of cases - does
updates.
In the patch those workloads were implemented to be executed by pgbench:
pgbench -b ycsb-A
