Bases:

- online_read(config: feast.repo_config.RepoConfig, table: feast.feature_view.FeatureView, entity_keys: List[feast.types.EntityKey_pb2.EntityKey], requested_features: Optional[List[str]] = None) List[Tuple[Optional[datetime.datetime], Optional[Dict[str, feast.types.Value_pb2.Value]]]] [source]
Read feature values given an Entity Key. This is a low level interface, not expected to be used by the users directly.
- Parameters
config – The RepoConfig for the current FeatureStore.
table – Feast FeatureView
entity_keys – a list of entity keys that should be read from the FeatureStore.
requested_features – (Optional) A subset of the features that should be read from the FeatureStore.
- Returns
Data is returned as a list, one item per entity key in the original order as the entity_keys argument. Each item in the list is a tuple of event_ts for the row, and the feature data as a dict from feature names to values. Values are returned as Value proto message.
- online_write_batch(config: feast.repo_config.RepoConfig, table: feast.feature_view.FeatureView, data: List[Tuple[feast.types.EntityKey_pb2.EntityKey, Dict[str, feast.types.Value_pb2.Value], datetime.datetime, Optional[datetime.datetime]]], progress: Optional[Callable[[int], Any]]) None [source]
Write a batch of feature rows to the online store. This is a low level interface, not expected to be used by the users directly.
If a tz-naive timestamp is passed to this method, it should be assumed to be UTC by implementors.
- Parameters
config – The RepoConfig for the current FeatureStore.
table – Feast FeatureView
data – a list of quadruplets containing Feature data. Each quadruplet contains an Entity Key,
values (a dict containing feature) –
row (an event timestamp for the) –
and –
exists. (the created timestamp for the row if it) –
progress – Optional function to be called once every mini-batch of rows is written to
progress. (the online store. Can be used to display) –
