Feast Quickstart

If you haven't already, check out the quickstart guide on Feast's website (http://docs.feast.dev/quickstart), which uses this repo. A quick view of what's in this repository's feature_repo/ directory:

• data/ contains raw demo parquet data
• feature_repo/feature_definitions.py contains demo feature definitions
• feature_repo/feature_store.yaml contains a demo setup configuring where data sources are
• feature_repo/test_workflow.py showcases how to run all key Feast commands, including defining, retrieving, and pushing features.

You can run the overall workflow with python test_workflow.py.

To move from this into a more production ready workflow:

See more details in Running Feast in production

1. First: you should start with a different Feast template, which delegates to a more scalable offline store.
   • For example, running feast init -t gcp or feast init -t aws or feast init -t snowflake.
   • You can see your options if you run feast init --help.
2. feature_store.yaml points to a local file as a registry. You'll want to setup a remote file (e.g. in S3/GCS) or a SQL registry. See registry docs for more details.
3. This example uses a file offline store to generate training data. It does not scale. We recommend instead using a data warehouse such as BigQuery, Snowflake, Redshift. There is experimental support for Spark as well.
4. Setup CI/CD + dev vs staging vs prod environments to automatically update the registry as you change Feast feature definitions. See docs.
5. (optional) Regularly scheduled materialization to power low latency feature retrieval (e.g. via Airflow). See Batch data ingestion for more details.
6. (optional) Deploy feature server instances with feast serve to expose endpoints to retrieve online features.
   • See Python feature server for details.
   • Use cases can also directly call the Feast client to fetch features as per Feature retrieval
