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
DELETEstatements in a workload via the
--deleteoption. This option works similar to the
--readsoption 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
BasicTimeSeriesworkload 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
Setsworkload 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.
