Limitation of OpenTelemetry support for Impala

Learn about the current limitations of OpenTelemetry support in Impala, including restricted scope and lack of customization.

The current OpenTelemetry integration for Impala has the following limitations:

Telemetry data scope

The scope of telemetry data is currently limited to only traces of select queries. Other types of data such as metrics or logs will not be handled in the initial release. However, the design is prepared to allow metrics or logs to be added in the future without significant architectural changes.

Select queries that leverage Common Table Expressions will not have traces generated for them.

Fixed trace data

The traces being sent from Impala are not configurable. This means you cannot customize the specific data points included in the traces.
