Azure Stream Analytics output error policy

This article describes the output data error handling policies that can be configured in Azure Stream Analytics.

Output data error handling policies apply only to data conversion errors that occur when the output event produced by a Stream Analytics job does not conform to the schema of the target sink. You can configure this policy by choosing either Retry or Drop. In the Azure portal, while in a Stream Analytics job, under Configure, select Error Policy to make your selection.

Retry

When an error occurs, Azure Stream Analytics retries writing the event indefinitely until the write succeeds. There is no timeout for retries. Eventually all subsequent events are blocked from processing by the event that is retrying. This option is the default output error handling policy.

Drop

Azure Stream Analytics will drop any output event that results in a data conversion error. The dropped events cannot be recovered for reprocessing later.

All transient errors (for example, network errors) are retried regardless of the output error handling policy configuration.
