Legion

Simple tool for running a procedure N times in T threads (using pmap). The motivation for this was quick and easy tinkering with different locking / concurrency features in postgresql. I could also see this being used as a simple load tester for a web site, database, or server.

Quickstart

# run the test procedure 100 times (serially) in 2 threads (concurrently)
lein run -c test -t 2 -n 100 -f legionfile

To create a new procedure, just add it to the legion file and run it with -c. For help text:

lein run -h
