Enum StoreProto.Store.StoreType

    • Enum Constant Detail

      • REDIS

        public static final StoreProto.Store.StoreType REDIS
         Redis stores a FeatureRow element as a key, value pair.
 The Redis data types used (https://redis.io/topics/data-types):
 - key: STRING
 - value: STRING
 
 Encodings:
 - key: byte array of RedisKey (refer to feast.storage.RedisKey)
 - value: byte array of FeatureRow (refer to feast.types.FeatureRow)
        REDIS = 1;

      • BIGQUERY

        public static final StoreProto.Store.StoreType BIGQUERY
         BigQuery stores a FeatureRow element as a row in a BigQuery table.
 
 Table name is derived is the same as the feature set name.
 
 The entities and features in a FeatureSetSpec corresponds to the 
 fields in the BigQuery table (these make up the BigQuery schema). 
 The name of the entity spec and feature spec corresponds to the column 
 names, and the value_type of entity spec and feature spec corresponds 
 to BigQuery standard SQL data type of the column. 
 
 The following BigQuery fields are reserved for Feast internal use. 
 Ingestion of entity or feature spec with names identical 
 to the following field names will raise an exception during ingestion.
   column_name       | column_data_type | description
 ====================|==================|================================
 - event_timestamp   | TIMESTAMP        | event time of the FeatureRow
 - created_timestamp | TIMESTAMP        | processing time of the ingestion of the FeatureRow
 - ingestion_id      | STRING           | unique id identifying groups of rows that have been ingested together
 - job_id            | STRING           | identifier for the job that writes the FeatureRow to the corresponding BigQuery table
 BigQuery table created will be partitioned by the field "event_timestamp"
 of the FeatureRow (https://cloud.google.com/bigquery/docs/partitioned-tables).
 
 The following table shows how ValueType in Feast is mapped to 
 BigQuery Standard SQL data types 
 (https://cloud.google.com/bigquery/docs/reference/standard-sql/data-types):
 BYTES       : BYTES 
 STRING      : STRING 
 INT32       : INT64
 INT64       : IN64 
 DOUBLE      : FLOAT64
 FLOAT       : FLOAT64 
 BOOL        : BOOL 
 BYTES_LIST  : ARRAY
 STRING_LIST : ARRAY
 INT32_LIST  : ARRAY
 INT64_LIST  : ARRAY
 DOUBLE_LIST : ARRAY
 FLOAT_LIST  : ARRAY
 BOOL_LIST   : ARRAY
 The column mode in BigQuery is set to "Nullable" such that unset Value
 in a FeatureRow corresponds to NULL value in BigQuery.
        BIGQUERY = 2;
