Version 1.12

New functionality

Query plan display

Added one of the most popular query plan analyzers based on the https://explain.tensor.ru service. The service is seamlessly integrated into the Tantor platform in 2 modes:

  1. Display any custom PostgreSQL query plans copied from any source and pasted into the service window;

  2. Mapping query plans. To do this, go to the Query Profiler -> <PlanHash> -> Plans section and select the query plan of interest.

This integration allows the user to perform analysis within the Tantor platform and does not require sending requests and data to external services. What’s more, the Tantor platform collects and stores queries according to the set configuration, making it much easier to find queries by parameters such as query time, number of rows, and more. More information can be found on the documentation page.
