This section explains the best practices to be followed when creating mediation sequences in the following scenarios.

...

• Use Iterator mediator in association with Aggregate mediator.

• Do not do any configuration after the Send mediator.

• Do proper error handling to handle mediation errors as well as endpoint errors.

• Use dollar context (i.e. $ctx)instead of using the get property.

  Info
  This is because the get-property methods search even in Registry if the value is not available in the message context. Thus, it affects performance as Registry search is an expensive operation. However, $ctx only checks in the message context.

• Use appropriate intervals for tasks.

• Use the ForEach mediator only for message transformations. If you need to make back-end calls from each iteration, then use the iterate mediator.

...

The Sequence mediator calls a Mediation Sequence saved in the Synapse configuration or the Registry with a unique name. The In, Out or Fault sequence of a proxy service, REST API or the Main sequence cannot be called via this mediator.

The correct usage of the ForEach mediator
