TrafficSplit(mapping=None, *, ignore_unknown_fields=False, **kwargs)

Traffic routing configuration for versions within a single service. Traffic splits define how traffic directed to the service is assigned to versions.

Attributes
Name	Description
shard_by	google.cloud.appengine_admin_v1.types.TrafficSplit.ShardBy Mechanism used to determine which version a request is sent to. The traffic selection algorithm will be stable for either type until allocations are changed.
allocations	MutableMapping[str, float] Mapping from version IDs within the service to fractional (0.000, 1] allocations of traffic for that version. Each version can be specified only once, but some versions in the service may not have any traffic allocation. Services that have traffic allocated cannot be deleted until either the service is deleted or their traffic allocation is removed. Allocations must sum to 1. Up to two decimal place precision is supported for IP-based splits and up to three decimal places is supported for cookie-based splits.

Classes

AllocationsEntry

AllocationsEntry(mapping=None, *, ignore_unknown_fields=False, **kwargs)

The abstract base class for a message.

Parameters
Name	Description
kwargs	dict Keys and values corresponding to the fields of the message.
mapping	Union[dict, .Message] A dictionary or message to be used to determine the values for this message.
ignore_unknown_fields	Optional(bool) If True, do not raise errors for unknown fields. Only applied if mapping is a mapping type or there are keyword parameters.

ShardBy

ShardBy(value)

Available sharding mechanisms.

Values: UNSPECIFIED (0): Diversion method unspecified. COOKIE (1): Diversion based on a specially named cookie, "GOOGAPPUID." The cookie must be set by the application itself or no diversion will occur. IP (2): Diversion based on applying the modulus operation to a fingerprint of the IP address. RANDOM (3): Diversion based on weighted random assignment. An incoming request is randomly routed to a version in the traffic split, with probability proportional to the version's traffic share.
