The Custom Pattern Formatter generates character string output. Do not use the Custom Pattern Formatter if the consumer application requires or expects a different format.

Do not use the Custom Pattern Formatter if the consumer application requires binary-encoded data. The Custom Pattern Formatter does not generate binary-encoded output. This guideline is also true for Data Engineering Streaming (DES) because it cannot consume binary-encoded messages. For more information, see If Informatica Data Engineering Streaming Will Consume Data from a Target.

Do not use the Custom Pattern Formatter with the Confluent Schema Registry. Confluent Schema Registry requires the Formatter.avroEncodingType property set to none. The Custom Pattern Formatter is only compatible with Formatter.avroEncodingType set to json.
