In the below paragraph,it has be corrected as 10MB instead of 0MB.Please correct the same.
By default (false), HTTP request payloads are read into a buffer, and policies that can operate on the payload work as expected. In cases where the payloads are larger than the buffer size (0 MB in Apigee Cloud, 3 MB in Edge for Private Cloud), you can set this attribute to true. When true, HTTP request payloads are not read into a buffer; they are streamed as-is to the TargetEndpoint request flow. In this case, any policies that operate on the payload in the ProxyEndpoint request flow are bypassed. See also
