> I'm planning to add some more load types to org.apache.derbyTesting.perf.clients.Runner
so that we can run tests whose load is roughly equivalent to the tests run in Olav's nightly
performance regression tests - http://home.online.no/~olmsan/derby/perf/. Having such tests
available would make it easier to investigate performance regressions reported by those test
runs. Currently, we have clients under o.a.dt.perf.clients that generate load that is similar
to the single-record select and single-record update operations with primary key and the primary
key join operations (in fact, the nightly regression tests have used the tests in derbyTesting.jar
for these types of load for about a month now).
> For the following types of load, we don't have test clients in derbyTesting.jar:
>   1) tests for insert performance
>   2) tests for delete performance
>   3) single-record select + single-record update on secondary index
>   4) single-record select + single-record update on non-indexed column
>   5) TPC-B like transactions (should probably be called something else, but I think it's
useful to have a test that uses the same schema and queries as described in the TPC-B spec)
> (3) and (4) are just variants over the existing single-record tests.
