Improvements​

  • New Object Browser screen to view Object details for tables, index and columns and their statistics.
    • In the Advanced section, we’ve introduced a new setting to control the collection of Object Statistics.
    • This feature reports on the statistical data collected about database objects—such as tables and indexes—which allows you to understand in more depth how the database optimiser arrived at its execution plans.
    • Collected statistics include row counts, distinct column values, object sizes, and a list of unused indexes.
    • You can navigate directly from elements with the execution plans to the object browser.
    • This functionality is currently available for both PostgreSQL and MySQL.
    • Additionally, the Info box now displays the hasobjectstatistics flag, indicating whether statistics have been collected.
  • When a host is deleted, a new “deletion in progress” status is now displayed, providing clearer feedback about the deletion process.

    • Recommendations now include detection of excessive SQL literals.

  • The granularity settings for Event History have been aligned with the rest of the product, ensuring a more consistent user experience, given that most events are only collected once per minute.
