Current Behavior
Could not import module 'hybrid_online_store'
Steps to reproduce
Use the following RepoConfig:
repo_config = RepoConfig(
**{
"project": "prod",
"registry": {
"registry_type": "sql",
"path": os.getenv("DATABASE_URL"),
"cache_ttl_seconds": 0,
"sqlalchemy_config_kwargs": {
"max_overflow": 50,
"pool_size": 5,
"pool_recycle": 3600,
},
},
"provider": "aws",
"entity_key_serialization_version": 3,
"online_store": {
"type": "hybrid_online_store.HybridOnlineStore",
"routing_tag": "store",
"online_stores": [
{
"type": "dynamodb",
"conf": {
"region": "us-east-1",
"max_pool_connections": 50,
"connect_timeout": 5,
"read_timeout": 10,
"total_max_retry_attempts": 2
}
},
{
"type": "redis",
"conf": {
"connection_string": os.getenv("REDIS_URL")
}
}
],
},
}
)
Specifications
- Version: 0.53.0
- Platform: macOs 14.6.1
- Subsystem: Python 3.12
Possible Solution
Use the following config:
repo_config = RepoConfig(
**{
"project": "prod",
"registry": {
"registry_type": "sql",
"path": os.getenv("DATABASE_URL"),
"cache_ttl_seconds": 0,
"sqlalchemy_config_kwargs": {
"max_overflow": 50,
"pool_size": 5,
"pool_recycle": 3600,
},
},
"provider": "aws",
"entity_key_serialization_version": 3,
"online_store": {
"type": "feast.infra.online_stores.hybrid_online_store.hybrid_online_store.HybridOnlineStore",
"routing_tag": "store",
"online_stores": [
{
"type": "dynamodb",
"conf": {
"region": "us-east-1",
"max_pool_connections": 50,
"connect_timeout": 5,
"read_timeout": 10,
"total_max_retry_attempts": 2
}
},
{
"type": "redis",
"conf": {
"connection_string": os.getenv("REDIS_URL")
}
}
],
},
}
)
Also, it's necessary to change the type attribute in hybrid_online_store.py (https://github.com/feast-dev/feast/blob/master/sdk/python/feast/infra/online_stores/hybrid_online_store/hybrid_online_store.py) from:
type: Literal["HybridOnlineStore", "hybrid_online_store.HybridOnlineStore"] = (
"hybrid_online_store.HybridOnlineStore"
)
To:
type: Literal["HybridOnlineStore", "feast.infra.online_stores.hybrid_online_store.hybrid_online_store.HybridOnlineStore"] = (
"hybrid_online_store.HybridOnlineStore"
)

I noticed this issue has been open for a while. I've submitted a fix in PR #5810 that adds the missing hybrid shorthand to ONLINE_STORE_CLASS_FOR_TYPE and the required __init__.py. Would appreciate a review when you have time! Reacted by Francisco Javier Arceo and Felipe Cordeiro Alves Dias fcas commented on Jan 26, 2026 @YassinNouh21 thanks a lot! I'll try to use this new version ASAP.
