[← All articles](/blog/) Article # Chronos chained events: multi-step workflow orchestration for real-time pipelines 6 Aug 2026 [Gluesync](/blog/?category=gluesync) 1 min read Evolve your data scheduling with Chronos chained events. Orchestrate multi-step pipeline sequences like historical snapshots followed by real-time CDC with built-in RBAC controls.  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](https://molo17.com/blog/gluesync-module-chronos-scheduler/)—one of the core [Gluesync Modules](https://molo17.com/blog/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: 1. **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.”_ 2. **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.
