Sagemaker Featurestore Runtime

batch_get_record(identifiers)
batch_get_record(identifiers, params::Dict{String,<:Any})

Retrieves a batch of Records from a FeatureGroup.

Arguments

• identifiers: A list of FeatureGroup names, with their corresponding RecordIdentifier value, and Feature name that have been requested to be retrieved in batch.

delete_record(event_time, feature_group_name, record_identifier_value_as_string)
delete_record(event_time, feature_group_name, record_identifier_value_as_string, params::Dict{String,<:Any})

Deletes a Record from a FeatureGroup in the OnlineStore. Feature Store supports both SOFTDELETE and HARDDELETE. For SOFTDELETE (default), feature columns are set to null and the record is no longer retrievable by GetRecord or BatchGetRecord. For HARDDELETE, the complete Record is removed from the OnlineStore. In both cases, Feature Store appends the deleted record marker to the OfflineStore with feature values set to null, isdeleted value set to True, and EventTime set to the delete input EventTime. Note that the EventTime specified in DeleteRecord should be set later than the EventTime of the existing record in the OnlineStore for that RecordIdentifer. If it is not, the deletion does not occur: For SOFTDELETE, the existing (undeleted) record remains in the OnlineStore, though the delete record marker is still written to the OfflineStore. HARD_DELETE returns EventTime: 400 ValidationException to indicate that the delete operation failed. No delete record marker is written to the OfflineStore.

Arguments

• event_time: Timestamp indicating when the deletion event occurred. EventTime can be used to query data at a certain point in time.
• feature_group_name: The name of the feature group to delete the record from.
• record_identifier_value_as_string: The value for the RecordIdentifier that uniquely identifies the record, in string format.

Optional Parameters

Optional parameters can be passed as a params::Dict{String,<:Any}. Valid keys are:

• "DeletionMode": The name of the deletion mode for deleting the record. By default, the deletion mode is set to SoftDelete.
• "TargetStores": A list of stores from which you're deleting the record. By default, Feature Store deletes the record from all of the stores that you're using for the FeatureGroup.

get_record(feature_group_name, record_identifier_value_as_string)
get_record(feature_group_name, record_identifier_value_as_string, params::Dict{String,<:Any})

Use for OnlineStore serving from a FeatureStore. Only the latest records stored in the OnlineStore can be retrieved. If no Record with RecordIdentifierValue is found, then an empty result is returned.

Arguments

• feature_group_name: The name of the feature group from which you want to retrieve a record.
• record_identifier_value_as_string: The value that corresponds to RecordIdentifier type and uniquely identifies the record in the FeatureGroup.

Optional Parameters

Optional parameters can be passed as a params::Dict{String,<:Any}. Valid keys are:

• "FeatureName": List of names of Features to be retrieved. If not specified, the latest value for all the Features are returned.

put_record(feature_group_name, record)
put_record(feature_group_name, record, params::Dict{String,<:Any})

Used for data ingestion into the FeatureStore. The PutRecord API writes to both the OnlineStore and OfflineStore. If the record is the latest record for the recordIdentifier, the record is written to both the OnlineStore and OfflineStore. If the record is a historic record, it is written only to the OfflineStore.

Arguments

• feature_group_name: The name of the feature group that you want to insert the record into.
• record: List of FeatureValues to be inserted. This will be a full over-write. If you only want to update few of the feature values, do the following: Use GetRecord to retrieve the latest record. Update the record returned from GetRecord. Use PutRecord to update feature values.

Optional Parameters

Optional parameters can be passed as a params::Dict{String,<:Any}. Valid keys are:

• "TargetStores": A list of stores to which you're adding the record. By default, Feature Store adds the record to all of the stores that you're using for the FeatureGroup.
