Next tlp-stress release - new features and changes

[Jon Haddad]

Hey folks,

It's been a little calm recently on the tools front, so I wanted to give a quick update on what's going into the next release. 

The biggest addition is support for deletes via the --delete flag (with a percentage).  Each workload will be responsible for how it handles it's own deletes, so it should fit in with the normal patterns you see.  For example, the BasicTimeSeries workload will delete all rows in a partition older than a certain timestamp.  Deletes are optional and default to off right now.

Since merging I've found a couple minor issues that need to be addressed, so I'm taking care of those before pushing it out as a release.

A potentially significant change that is coming down the line has to do with pagination.  Right now, only the first page of a query is fetched, meaning the numbers that come back for very large partitions can be misleading.  The new behavior will paginate through the entire partition before marking the query as complete.  This will give a more accurate view of the cluster and what it is capable of. 

Looking forward to hearing your feedback.

Jon
