Chains

A chain combines multiple flows into a single executable process.

Chains are used when several flows need to be executed in a controlled order. Flows can be added to a chain sequentially or in parallel. Parallel flows are distributed across the available CPU cores. The chain stores dependencies between flows, so Belt understands the execution order, parallel branches, and the overall process status.

A chain can be started with the Run button or scheduled for periodic execution.

The Monitoring button opens the visual monitoring mode for chain runs. A calendar is displayed on the left side. By clicking a specific run, the user can open its visual execution view. Nodes are highlighted according to their status: green — completed successfully, yellow — running, and red — error. If at least one node in the chain has an error, the entire chain is marked with the error status.
