== Using Eventing

You can use Eventing and Sync Gateway connected to the same bucket, when Eventing operates in *read only* mode.
You can use Eventing and Sync Gateway connected to the same bucket, when Eventing operates on server buckets in *read only* mode -- see {server-eventing-terminologies--xref-bindings} for how to do this.

To do this, you must write your Eventing function to be *idempotent*; to behave correctly when the same mutation is seen more than once.
You should write your Eventing function to be *idempotent*; to behave correctly when the same mutation is seen more than once.
This is necessary because:

* When a single document update is made directly by Sync Gateway, such as those replicated from Couchbase Lite, it generates a single server mutation that writes both the document body and the metadata.
