• rpc StreamSnapshot (StreamSnapshotRequest, stream StreamSnapshotResponse)

  replica_state_snapshot.proto:26

  Stream a specific state snapshot in a resumable fashion as a finite stream of key-values. Key-values are streamed with lexicographic order on keys. Errors: NOT_FOUND: if a state snapshot with the requested ID is not (or no longer) available. Clientservice must retry by fetching a new snapshot ID. INVALID_ARGUMENT: if resuming a stream using `last_received_key` and that key is not part of the state snapshot. UNAVAILABLE: if the Concord replica is not ready yet to process requests. For example, the snapshot with the given ID is still being created at the time of the request. UNKNOWN: exact cause is unknown.

  message StreamSnapshotRequest

  replica_state_snapshot.proto:29

  • uint64 snapshot_id = 1

    The ID of the state snapshot to be streamed.

  • optional bytes last_received_key = 2

    If set, start streaming from `last_received_key` onwards, excluding `last_received_key`. If `last_received_key` is not part of the state snapshot, an INVALID_ARGUMENT error is returned. If not set, start streaming from the first key-value in the state snapshot. The empty bytestring is a valid key. Key-values are streamed with lexicographic order on keys.

  message StreamSnapshotResponse

  replica_state_snapshot.proto:51

  • optional KeyValuePair key_value = 1

Used in: StreamSnapshotResponse

• bytes key = 1

• bytes value = 2
