Victoria Series Release Notes

3.0.0

Upgrade Notes

  • Python 2.7 support has been dropped. The minimum version of Python now supported by osprofiler is Python 3.6.

2.8.0

New Features

  • Redis storage schema is optimized for higher performance. Previously Redis driver stored each tracing event under its own key, as result both list and get operations required full scan of the database. With the optimized schema traces are stored as Redis lists under a key equal to trace id. So list operation iterates only over unique trace ids and get operation retrieves content of a specified list. Note that list operation still needs to retrieve at least 1 event from the trace to get a timestamp.

Upgrade Notes

  • The optimized Redis driver is backward compatible: while new events are stored using new schema the driver can retrieve existing events using both old and new schemas.

1.6.0

Other Notes

  • Introduce reno for deployer release notes.
