Error Handling

Stream workers in Macrometa Global Data Network handle errors at the source, in the stream processing, and at the sink.

Errors at Source

Errors emitted by stream elements are managed by the OnError.action='stream' property within the stream definition. This property ensures that errors, along with the events that caused them, are sent to a fault stream, named using the !<StreamName> syntax.

For more information, refer to Error Handling at Source.

Errors at Sink

For sinks, the same OnError.action='stream' property can be used to capture and handle errors. This ensures that any issues during the event publication process are properly managed.

For more information, refer to Error Handling at Sink.

Errors in Stream Processing

The OnError.action='stream' property is also applicable to errors that occur within stream processing. It automatically redirects errors to a fault stream.

For more information, refer to Error Handling in Stream Processing.

Errors in Table Operations

Errors that occur during table operations, such as insertions, deletions, or updates, are now handled by the OnError.action='stream' property. This ensures that any issues encountered during table operations are captured and directed to a fault stream specific to that table, indicated by !<TableName>.
