Tarantool Cluster Manager 1.3

TCF page improvements

Starting from version 1.3.0, TCM provides additional actions for managing TCF clusters through the web interface. You can now use promote and demote operations directly on the TCF page without switching to external tools. Also, the TCF page is now disabled by default and must be explicitly enabled if needed. In addition, TCM now supports connections to multiple gRPC servers, which improves integration with distributed cluster infrastructures.

Explorer improvements

TCM 1.3.0 introduces a new approach to pagination in the Explorer. Instead of using a tuple, the interface now relies on pointers for navigating result pages. When sending data to the frontend, binary values (varbinary) are now automatically encoded in base64.

Additionally, TCM fixes an issue where queries using a datetime key could result in type mismatch errors due to incorrect index part handling.

etcd integration fixes

In this version, TCM improves its interaction with etcd-based data sources. Tabs that use etcd for updating can now be refreshed even if some of the etcd endpoints are temporarily unavailable. To improve stability, a check was added to detect and correctly handle empty tuple arrays, preventing unexpected errors when processing empty data.

CRUD and query parsing

TCM 1.3.0 includes improvements to how search expressions are parsed in CRUD explorer queries. The CRUD explorer is located on the Tuples page. This release also introduces dedicated tests for the relevant components to ensure consistent behavior in future versions.

Since version 1.3.1, TCM includes missing changes that have now been properly delivered. In addition, several minor issues flagged by the Svacer linter were fixed to improve overall code quality and maintainability.
