Which is idempotent put or POST?

Is rest POST idempotent?

An idempotent HTTP method is a HTTP method that can be called many times without different outcomes. It would not matter if the method is called only once, or ten times over.

What is idempotent in Kafka?

Kafka has support for idempotence through Idempotent Producer / Exactly Once semantics. Means it ensures that messages published on Kafka topics should not be duplicated from the Producer side. In case of an error, the producer retries the same message. But Kafka logs this message only once on the broker.

What are idempotent methods?

An HTTP method is idempotent if an identical request can be made once or several times in a row with the same effect while leaving the server in the same state. In other words, an idempotent method should not have any side-effects (except for keeping statistics).
