google.cloud.discoveryengine_v1alpha.types.Engine.RecommendationMetadata.DataState
Output only. The state of data requirements for this engine:
DATA_OK and DATA_ERROR.
Engine cannot be trained if the data is in DATA_ERROR
state. Engine can have DATA_ERROR state even if serving
state is ACTIVE: engines were trained successfully
before, but cannot be refreshed because the underlying
engine no longer has sufficient data for training.
last_tune_time
google.protobuf.timestamp_pb2.Timestamp
Output only. The timestamp when the latest
successful tune finished. Only applicable on
Media Recommendation engines.
tuning_operation
str
Output only. The latest tune operation id
associated with the engine. Only applicable on
Media Recommendation engines.
If present, this operation id can be used to
determine if there is an ongoing tune for this
engine. To check the operation status, send the
GetOperation request with this operation id in
the engine resource format. If no tuning has
happened for this engine, the string is empty.
Classes
DataState
DataState(value)
Describes whether this engine have sufficient training data
to be continuously trained.
