Chronos chained events: multi-step workflow orchestration for real-time pipelines

Traditional job schedulers excel at basic time-based triggers—running a script every night at 3:00 AM. However, real-time data replication architectures require coordinated operational sequences. For example, before launching continuous log-based Change Data Capture (CDC), an engine must first complete a historical table snapshot without risking data drift or partial loads.
To address these enterprise requirements, Chronos Scheduler—one of the core Gluesync Modules—has evolved from a basic schedule manager into a full multi-step workflow orchestration engine.
Synchronous vs. asynchronous execution modes
The core enhancement in Chronos is chained events: the ability to execute sequences of actions one after another with explicit dependency controls.
Engineers can configure chained events in two operational modes:
- Synchronous execution: Chronos executes a step and waits for a completion callback before firing the next action in the sequence. This mode is critical for dependent tasks like “complete initial historical snapshot first, then initiate real-time log streaming.”
- Asynchronous execution: Chronos fires event triggers in a non-blocking, fire-and-forget sequence, ideal for independent notification flows or parallel pipeline kickoffs.
Visual management and enterprise guardrails
Workflow orchestration is integrated directly into the Gluesync Control Plane:
Visual chained-events editor
Built into the redesigned Scheduler UI, allowing operators to build, review and adjust event dependencies visually without manual code edits.
Flexible schedule syntax
Supports both visual weekly schedule pickers and custom CRON expressions, complete with timezone configuration and manual “run-now” triggers.
Performance optimizations
Chronos features batch query loading (resolving N+1 database bottlenecks), cached timezone resolution and pre-calculated next_run execution schedules for faster startup times.
Role-based access control (RBAC)
Gated behind JWT authentication validated against Core Hub (/auth/me), ensuring that schedule creation, modification or execution is restricted by user roles (SUPER_ADMIN, MANAGER, MONITOR, VIEWER).
Chronos chained events ensure that multi-stage data integration tasks execute in perfect order with zero manual intervention. For setup examples and payload schemas, visit the official Chronos Chained Events Documentation.
