-## HTTP Request Body Max Byte size
-
-To prevent OOM attacks through excessively large request bodies, a default limit is posed on request body size of `100kb`. This limit is generally speaking ample space for GraphQL request bodies, while also providing solid protections.
-
-You can modify this limit by changing the following configuration option
-
-```yaml
-web:
-  # limit the maximum size of a request body that is allowed
-  # this helps prevent OOM attacks through excessively large request payloads.
-  # A limit of `0` disables this protection.

-A metric is exposed to track if and when a request is rejected that exceeds this limit.
