Play back events for diagnostics, testing, or in case of failures.
RudderStack’s event replay feature lets you back up your event data and replay it in case of any failures. Some scenarios where you can leverage this functionality include:
Replay failed events from a particular date to a destination, maybe due to some misconfiguration.
Replay all events for a particular source, from a particular date, to a new event stream or warehouse destination.
Supported event types for replay
RudderStack can store the following types of event data and replay it to the specified destinations:
Raw events captured through various sources. RudderStack stores these events in batches of 100,000 events.
Event payloads sent by RudderStack in case of delivery failures along with the errors (stored approximately every 30 seconds).
Data retention options
RudderStack offers the following data retention options for event replay functionality:
Do not store event data (default): RudderStack does not store any event data and hence it cannot be replayed.
Store in your own cloud storage (recommended): Event data is stored in your object storage. RudderStack currently supports Amazon S3, Google Cloud Storage, Azure Blob Storage, and MinIO as the object storage options.
Store in RudderStack Cloud storage: Event data is stored in RudderStack’s Amazon S3 bucket on a rolling 30-day basis. That is, RudderStack deletes the event data 30 days after it was stored.
To learn more about these data retention options, refer to the Data Management guide.
Object storage setup
If you choose to set up your own object storage for backing up and replaying the events, follow the steps below depending on your cloud provider:
Depending on how you store your event data (RudderStack-hosted storage or your own object storage), you can contact the Customer Success team to safely replay your events and avoid any unfavorable circumstances.
