def exclude_replicas() -> ::Google::Cloud::Spanner::V1::DirectedReadOptions::ExcludeReplicas

Returns

(::Google::Cloud::Spanner::V1::DirectedReadOptions::ExcludeReplicas) — Exclude_replicas indicates that specified replicas should be excluded from serving requests. Spanner will not route requests to the replicas in this list.

def exclude_replicas=(value) -> ::Google::Cloud::Spanner::V1::DirectedReadOptions::ExcludeReplicas

Parameter

value (::Google::Cloud::Spanner::V1::DirectedReadOptions::ExcludeReplicas) — Exclude_replicas indicates that specified replicas should be excluded from serving requests. Spanner will not route requests to the replicas in this list.

Returns

(::Google::Cloud::Spanner::V1::DirectedReadOptions::ExcludeReplicas) — Exclude_replicas indicates that specified replicas should be excluded from serving requests. Spanner will not route requests to the replicas in this list.

def include_replicas() -> ::Google::Cloud::Spanner::V1::DirectedReadOptions::IncludeReplicas

Returns

(::Google::Cloud::Spanner::V1::DirectedReadOptions::IncludeReplicas) — Include_replicas indicates the order of replicas (as they appear in this list) to process the request. If auto_failover_disabled is set to true and all replicas are exhausted without finding a healthy replica, Spanner will wait for a replica in the list to become available, requests may fail due to DEADLINE_EXCEEDED errors.
