stress 2.0 released

[Jon Haddad]

Hey folks,

Today we released version 2.0 of tlp-stress.  There's a handful of quality of life improvements and a couple bug fixes.

#98 When writing results to a csv via the --csv option, we now include the command used to start tlp-stress in a comment at the top of the CSV

#96 We now allow for a TLP_STRESS_CASSANDRA_HOST variable to be set that changes the default --host.  This will allow for less verbose commands and make it easier for teams to share the same configuration across clusters

#82 We've added log rotation by default.  This was an oversight that could result in disks filling up.  Logs are now stored under the ~/.tlp-stress directory.

#89 You can specify a different Cassandra port other than 9042 with the --port flag

#80 A shorthand now exists for changing compaction strategies from the default.  For example, you can now use --compaction lcs or --compaction twcs, or even --compaction twcs,1,hours.  There are a handful of shorthand options, see the compaction shorthand section in the docs to learn more: http://thelastpickle.com/tlp-stress/

We don't intend on putting out big releases, we believe in releasing often.  Please get us your feedback!

Is there any documentation or pointer to how to add custom workload with tlp-stress? 

thanks

Not yet, although that will happen very soon.  Adding a workload right now means working with the project itself rather than pulling in a dependency.  If you're willing to give it a shot, it isn't too bad.  I created this one in maybe 30 minutes: https://github.com/thelastpickle/tlp-stress/blob/master/src/main/kotlin/com/thelastpickle/tlpstress/profiles/AllowFiltering.kt

If you put a new class in the profiles directory it'll get picked up automatically when tlp-stress starts up.  The intent is to later allow folks to drop their own JARs into the lib directory.
