Subject [jira] Updated: (DERBY-3619) Implement more load types for org.apache.derbyTesting.perf.clients.Runner
Date Fri, 18 Apr 2008 13:44:21 GMT

     [ https://issues.apache.org/jira/browse/DERBY-3619?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Knut Anders Hatlen updated DERBY-3619:
--------------------------------------

    Attachment: lob.diff

The attached patch makes it possible to run the single-record select tests with a blob or
clob column instead of a varchar column. "-load sr_select" uses VARCHAR(100), "-load sr_select_blob"
uses BLOB(100) and "-load sr_select_clob" uses CLOB(100).

> 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.
