Optimizing Multi-Database Operations with Execute Query

Executing queries across multiple MySQL databases is motivated by several key needs:

  • Consolidation of Information: Combining data from different databases allows for comprehensive analytics and reporting.

  • Cross-Database Operations: Operations such as joining tables from separate databases are essential for generating combined datasets.

  • Resource Optimization: Utilizing databases optimized for specific workloads or data sets enhances performance.

  • Access Control and Security: Managing data across separate databases helps control access and enhance security.

  • Simplifying Data Management: Cross-database queries prevent the need for complex data migration, easing data management.

Execute Query main view


This view allows the user to run queries on multiple database servers simultaneously.

Execute Query is an engine that allows Dev or Ops team to execute any SQL command, or Script against, one or thousands of targets. Out of the Box, the Execute Query engine comes with pre-defined SQL scripts that are covering a lot of use cases, and can support any scripts that you write. Like the Execute Query engine itself, the templates are also divided into 2 main categories.
