Benefits of OTel Impala Integration

Integrating OTel with Impala provides enhanced observability through comprehensive data collection. The following data is collected:

• Live query data – Data about important events in the lifecycle of actively running queries is sent to collectors in near real-time as the events happen.
• Historical query data – Data about completed queries can be retained by the destination OTel trace management system.

The integration is designed to have negligible impact on Impala's performance and is built for scalability. The following performance and scalability impacts are valid for the integration:

• The performance impact on Impala is negligible because the system already collects all the necessary event and metric data.
• The process of sending data to the OTel endpoint is handled out-of-band in a separate thread, limiting any performance impact to just the sending of this data.
• Scalability concerns are primarily limited to the OTel Collector endpoint. Impala does not encounter scalability issues as long as communication with the Collector happens without delay.
