gRPC Fail Fast Semantics |
Moved to wait-for-ready.md |
||||||
======================== |
|
||||||
|
|
||||||
Fail fast requests allow terminating requests (with status UNAVAILABLE) prior |
|
||||||
to the deadline of the request being met. |
|
||||||
|
|
||||||
gRPC implementations of fail fast can terminate requests whenever a channel is |
|
||||||
in the TRANSIENT_FAILURE or SHUTDOWN states. If the channel is in any other |
|
||||||
state (CONNECTING, READY, or IDLE) the request should not be terminated. |
|
||||||
|
|
||||||
Fail fast SHOULD be the default for gRPC implementations, with an option to |
|
||||||
switch to non fail fast. |
|
||||||
|
|
||||||
The opposite of fail fast is 'ignore connectivity'. |

gRPC Wait for Ready Semantics |
||||||
|
============================= |
||||||
|
|
||||||
|
If an RPC is issued but the channel is in `TRANSIENT_FAILURE` or `SHUTDOWN` |
||||||
|
states, the RPC is unable to be transmited promptly. By default, gRPC |
||||||
|
implementations SHOULD fail such RPCs immediately. This is known as "fail fast," |
||||||
|
but usage of the term is historical. RPCs SHOULD NOT fail as a result of the |
||||||
|
channel being in other states (`CONNECTING`, `READY`, or `IDLE`). |
||||||
|
|
||||||
|
gRPC implementations MAY provide a per-RPC option to not fail RPCs as a result |
||||||
|
of the channel being in `TRANSIENT_FAILURE` state. Instead, the implementation |
||||||
|
queues the RPCs until the channel is `READY`. This is known as "wait for ready." |
||||||
|
The RPCs SHOULD still fail before `READY` if there are unrelated reasons, such |
||||||
|
as the channel is `SHUTDOWN` or the RPC's deadline is reached. |
