SnowflakeOfflineStoreConfig import fails in the python feature server

[jerive]

Expected Behavior

Configuring snowflake does not make the AWS python server fail

Current Behavior

[ERROR] FeastModuleImportError: Could not import module 'feast.infra.offline_stores.snowflake' 
while attempting to load class 'SnowflakeOfflineStoreConfig'

Steps to reproduce

• Configure a snowflake offline store
• Deploy the AWS python feature server
• Query /get-online-features

Specifications

• Version: v0.20.0
• Platform:
• Subsystem: Python feature server AWS

Possible Solution

Hi @jerive , you're right that this is indeed a bug. We're planning on fixing this in a patch release soon (hopefully this week)

More context: The AWS Feature Server dockerfile doesn't install the snowflake extra, and feast by design eagerly loads the offline store.

Ideally, we should instantiate the offline store lazily so that we don't load it in environments like feature serving, where it's not neeeded.
