Version 4.0 of tlp-stress for Cassandra released

The Last Pickle is very pleased to announce that version 4.0 of tlp-stress for Apache Cassandra has been released.

Here is what you will find in the release:

  • The biggest addition is support for including DELETE statements in a workload via the --delete option. This option works similar to the --reads option where a value between 0 and 1 is supplied with the argument. Each workload is responsible for creating the delete requests. So they naturally fit in with each of the workload patterns. As a result of this new feature, the BasicTimeSeries workload works with only Cassandra versions 3.0 and above. See the tlp-stress documentation for more information.

  • Support for adjusting the maximum requests per connection via the --max-request option.

  • A new Sets workload to exercise the set collection type. This was useful for investigating the root cause of slow inserts to set<text>. See CASSANDRA-15464.

  • Improved error handling for non-existent workload parameters, non-existent workloads, and when the read rate plus the delete rate is greater than 1.0.

  • Documentation updates to reflect the new option and workload additions.

A complete list of the items covered in the release can be found in the tlp-stress GitHub issues under the 4.0 milestone.

As always binaries for the release can be found in The Last Pickle Bintray and Docker Hub repositories.
