Ordering Status and Reads in the gRPC API |
|
----------------------------------------- |
|
|
|
Rules for implementors: |
|
1. Reads and Writes Must not succeed after Status has been delivered. |
|
2. OK Status is only delivered after all buffered messages are read. |
|
3. Reads May continue to succeed after a failing write. |
|
However, once a write fails, all subsequent writes Must fail, |
|
and similarly, once a read fails, all subsequent reads Must fail. |
|
4. When an error status is known to the library, if the user asks for status, |
|
the library Should discard messages received in the library but not delivered |
|
to the user and then deliver the status. If the user does not ask for status |
|
but continues reading, the library Should deliver buffered messages before |
|
delivering status. The library MAY choose to implement the stricter version |
|
where errors cause all buffered messages to be dropped, but this is not a |
|
requirement.
