GrpcRouteSpecOptions

class aws_cdk.aws_appmesh.GrpcRouteSpecOptions(*, priority=None, match, weighted_targets, retry_policy=None, timeout=None)

Bases: RouteSpecOptionsBase

Properties specific for a GRPC Based Routes.

Parameters:

  • priority (Union[int, float, None]) – The priority for the route. When a Virtual Router has multiple routes, route match is performed in the order of specified value, where 0 is the highest priority, and first matched route is selected. Default: - no particular priority

  • match (Union[GrpcRouteMatch, Dict[str, Any]]) – The criterion for determining a request match for this Route.

  • weighted_targets (Sequence[Union[WeightedTarget, Dict[str, Any]]]) – List of targets that traffic is routed to when a request matches the route.

  • retry_policy (Union[GrpcRetryPolicy, Dict[str, Any], None]) – The retry policy. Default: - no retry policy

  • timeout (Union[GrpcTimeout, Dict[str, Any], None]) – An object that represents a grpc timeout. Default: - None

            metadata=[
