Sysbench with support of multi-tables workload

 | April 29, 2011 |  Posted In: MySQL


We just pushed to sysbench support for workload against multiple tables ( traditionally it used only single table).

It is available from launchpad source tree lp:sysbench .

This is set of LUA scripts for sysbench 0.5 ( it supports scripting), and it works following way:

– you should use --test=tests/db/oltp.lua to run OLTP test
i.e. prepare


oltp.lua should understand most options that available for regular sysbench –test=oltp

there are couple other scripts, like

to support different OLTP modes.

Most interesting: all scripts support --oltp-tables-count=N ( default 1), in this case N sbtest tables will be used.

Additional parameter --oltp-secondary is taken from Mark Callaghan’s sysbench tree , in this case
table sbtest will be created with KEY xid (ID) , instead of PRIMARY KEY (ID)

Now, as we have N tables, we may want to prepare them in parallel, to save some time for preparation
I implemented that in script parallel_prepare.lua

so instead of

you may use

( please note that oltp-tables-count should be multiplier of num-threads)
