Fill in the newatoti.Dimension.descriptionto give it more context about the data model.atoti_ai.AutoExplainsurfaces the hierarchies and members that best explain a measure’s variation, speeding up root-cause analysis.AggregateProviders.recommenderanalyzes aCube’s query traffic and recommends the most impactfulAggregateProvidercoverage for it.
Limits plugin
Theatoti-limits plugin connects an Atoti session to a Limits server and adds the Limits app extension to Atoti UI.Query History
When theobservability plugin is enabled and atoti.SessionConfig.user_content_storage is not None, the history of executed queries is recorded and accessible in Admin UI’s Query history tab.Improvements
Upgraded dependencies
- Bumped the minimum required Python version to 3.12 as per NEP 29.
- Bumped the minimum required Pandas version to 3.0.3.
- Aligned Atoti Python SDK’s version with Atoti Server.
Going forward, each
6.2.xPython SDK release depends on the matching6.2.xServer release, making compatibility obvious at a glance.
Safer data loading default
atoti.Table.load(error_handling) defaults to "fail" instead of "log", so loading errors surface immediately instead of being silently logged.
