Description

The Snowflake online store provides support for materializing feature values into a Snowflake Transient Table for serving online features.
  • Only the latest feature values are persisted
The data model for using a Snowflake Transient Table as an online store follows a tall format (one row per feature)):
  • "entity_feature_key" (BINARY) -- unique key used when reading specific feature_view x entity combination
  • "entity_key" (BINARY) -- repeated key currently unused for reading entity_combination
  • "feature_name" (VARCHAR)
  • "value" (BINARY)
  • "event_ts" (TIMESTAMP)
  • "created_ts" (TIMESTAMP)
(This model may be subject to change when Snowflake Hybrid Tables are released)
