Activation of idempotence (exactly once semantic) - Kafka target endpoint

[RobertBARRAS]

Hi

I know idempotence is disabled by default in the kafka endpoint.

Would you plz describe how and where we can change this parameter ("enable.idempotence","true")?

By the way, would you also give some feedback about the performances if we activate this option?

Thank you.

Hello @RobertBARRAS ,

In general Qlik Replicate does not set additional parameters unless it's required in Kafka target endpoint. For "enable.idempotence" it's default value is FALSE in Kafka Configuration properties . Replicate inherits the default value. You may change it if needed.

Regarding the performance impact, it may or may not. Seems we have not a prove of the impact till now.

Hope this helps.

Regards,

John.
