Feature Service API (1.0)

License: Proprietary

Tecton provides a low-latency feature server that exposes HTTP endpoints to retrieve feature values and metadata from the online store. These endpoints are typically used during model predictions. The feature servers retrieve data from the online store and perform any additional aggregations and filtering as necessary.

GetFeatures

Get Features API to retrieve feature values from Tecton's online store

Authorizations:
Tecton_API_Key
Request Body schema: application/json
object (GetFeaturesParameters)

Parameters for get-features.

Exactly one of featureServiceName and featureServiceId must be set.

featureServiceId
string

FeatureService ID. Exactly one of this field and featureServiceName must be set.

featureServiceName
string

FeatureService name. Exactly one of this field and featureServiceId must be set.

workspaceName
string
joinKeyMap
object

Join keys used for Batch and Stream FeatureViews.

The key of this map is the join key name and the value is the join key value for this request. The values are encoded as follows:

  • For string keys, the value should be a string.
  • For int64 keys, the value should be a string of the decimal representation of the integer.
requestContextMap
object

Request context used for OnDemand FeatureViews.

The key of this map is the request context key name and the value is the request context value for this request. The values are encoded as follows:

  • For string values, the value should be a string.
  • For int64 values, the value should be a string of the decimal representation of the integer.
  • For double values, the value should be a number.
object (MetadataOptions)

Options for retrieving additional metadata about the feature values.

allowPartialResults
boolean
Default: "false"

Whether incomplete results should be returned when the Online Feature Store size limit has been exceeded for this request. If this is not true, then the response will be an error in this case.

This is an advanced option and should only be set after consulting with the Tecton team.
