Sync call

Sequencer inside one flow: sends the record to Output, waits until that branch has completed, then sends the same record to Continue. Use it to run "first this, then that" with the same data. It does not call other flows.

Pins

Pin	Kind	Types	Description
Input	input	any	Record to process.
Output	output	same as input	Called first, synchronously.
Continue	continue	same as input	Called after the Output branch has returned.

Configuration

None besides the common settings.

Behaviour

• Calls Output with the record and metadata and waits for the whole branch (all connections, one after another). Then calls Continue with the same record and metadata.
• If the Output branch throws an exception, Continue is not called and the exception is passed back to the caller (e.g. to a Try catch upstream).
• An unconnected Output or Continue is skipped.

Notes

• Changes made to the record or metadata in the Output branch are visible in the Continue branch (same instances).
• Only synchronous work is awaited. Work handed to other threads in the Output branch (queues, Start flow, async callbacks) may still run when Continue is called.
• To call another flow and get its result, build that flow as a flow plugin ("Plugin port" entry point and "Plugin port response") and use it as a component; to only trigger another flow use Start flow.

Example

Timer → Database reader → Sync call → (Output) Http client ; (Continue) Database writer (mark as sent)
