FeatureSpec

Configuration description of features to be queried, which is applicable to the non-automatic graph modification mode.

Parameter	Data Type	Mandatory/Optional	Description
index_key	int/string	Optional	Index key Default value: value of table_name. Value range: Int: The value range is [0,255]. String: The length range is [1,255].
table_name	string	Optional	Table name Table name length range: [1, 255]
access_threshold	int	Optional	Feature access threshold. Value range: [–1, 2147483647] 0: access is enabled. The number of key occurrences in the new batch is not accumulated. The historical feature count is used. Greater than 0: access is enabled. The number of key occurrences in the new batch is accumulated and the feature count record is updated. -1: access is disabled.
eviction_threshold	int	Optional	Feature eviction threshold Value range: [–1, 2147483647] Greater than or equal to 0: eviction is enabled. -1: eviction is disabled. If you need to set the feature eviction threshold, you also need to set the feature access threshold.
is_timestamp	bool	Optional	Whether a timestamp used Value range: True False
batch_size	int	Optional	Batch size of a dataset Value range: [1, 2147483647]
faae_coefficient	int	Optional	Feature access coefficient Default value: 1 Value range: [1, 2147483647]
name	string	Mandatory	FeatureSpec name Value length: [1,255]

Example

from mx_rec.core.asc.feature_spec import FeatureSpec
feature_spec_list = FeatureSpec("user_ids", table_name="user_table",
                                access_threshold=1,
                                eviction_threshold=1,
                                faae_coefficient=1)
