Limitations
In the current release, this feature has the following limitations:
-
The PCF attempts to reroute the calls only when it encounters gRPC errors such as UNAVAILABLE. It does not acknowledge errors that the datastore returns and actual gRPC timeouts such as DEADLINE_EXCEEDED gRPC status code.
-
The PCF Engine does not resolve failures occurring with the datastore such as indexing and slot failures. The CDL layer must resolve these failures and if necessary, send an API call on the remote.
