Snowflake data sources allow for the retrieval of historical feature values from Snowflake for building training datasets as well as materializing features into an online store.

• Either a table reference or a SQL query can be provided.

Using a table reference

from feast import SnowflakeSource

my_snowflake_source = SnowflakeSource(
    database="FEAST",
    schema="PUBLIC",
    table="FEATURE_TABLE",
)

Using a query

from feast import SnowflakeSource

my_snowflake_source = SnowflakeSource(
    query="""
    SELECT
        timestamp_column AS "ts",
        "created",
        "f1",
        "f2"
    FROM
        `FEAST.PUBLIC.FEATURE_TABLE`
      """,
)

One thing to remember is how Snowflake handles table and column name conventions. You can read more about quote identifiers here
