Distributor error handling

Component: Distributor

NServiceBus provides error handling and has Immediate Retries and Delayed Retries.

When using the distributor the behavior of retries and the related message flow is different between major versions.

Immediate Retries

Immediate Retries are always performed on the worker.

Delayed Retries

The behavior of Delayed Retries is different between major versions.

Delayed Retries has two configurable items TimeIncrease and NumberOfRetries.

The message will be retried on any available worker. Message processing is not sticky to the worker.

partial: retries

Best practice

Due to the behavioral differences between major versions it is advised to have the SecondLevelRetriesConfig exactly the same on both the distributor and the workers even though it could be that settings are ignored.

It is assumed that NumberOfRetries and TimeIncrease are the same on the distributor and the workers.

If settings are managed in XML configuration all changes in the distributor configuration need to be replicated to all nodes.
