pub async fn connect_and_hello(compute_addr: &str) -> Result<ComputeCtpClient>Expand description
Connects to a clusterd compute controller address and sends Hello, leaving
the controller handshake (CreateInstance onward) to the caller.
A reconnect re-runs exactly this: a fresh transport connection plus Hello.
The reconciliation window then opens when the script sends CreateInstance
and closes when it sends InitializationComplete; in between, the replica
reconciles the replayed dataflows against its live ones rather than
rehydrating.
