Run behavior & recovery

API Composer

• Only one run per sequence or stand-alone request can be active at a time.
• A Fatal failure skips the remaining requests; a Functional failure allows the sequence to continue.
• Aborting does not undo rows already written.
• With polling enabled, output is written only when the Continue rule matches.
• A rate-limit response is retried automatically according to the documented limits.
• Truncate and Insert clears the target data set at the start of the run and has no undo.

Dataflow Composer

• Only one import per dataflow runs at a time.
• The existing output remains available until a new import succeeds completely.
• A failed or aborted import leaves the previous output unchanged.
• Every successful import replaces the complete output data set.

Endpoint Composer

When a write call contains several records, successful records remain written even when other records fail. The response reports failures per record, so callers must not interpret a partly failed response as an all-or-nothing transaction.
