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.
