dynamodb doesn't seem to support materialization of multiple feature views having the same entity and join keys

[boumelhaa]

Expected Behavior

let's say i have 2 feature views:

account_fv1 = FeatureView(
    name="account_fv1",
    entities=[account_entity, country_entity],
    ttl=timedelta(weeks=1 * 5),  # Set to be very long for example purposes only
    schema=[
        Field(name="feature_1", dtype=String),
        Field(name="feature_2", dtype=String),
    ],
    source=account_engagement_source,
    tags={"team": "ranking"},
)

account_fv2 = FeatureView(
    name="account_fv2",
    entities=[account_entity, country_entity],
    ttl=timedelta(weeks=1 * 5),  # Set to be very long for example purposes only
    schema=[
        Field(name="some_other_feature", dtype=String),
        Field(name="some_other_feature", dtype=String),
    ],
    source=account_engagement_source,
    tags={"team": "ranking"},
)

I expect when materializing separately, this feature view to Dynamo to be able to retrieve both of them.

Current Behavior

the last materialized feature view overrides the one materialized before because they have the same entity_id

Steps to reproduce

• Version:latest
• Platform:linux and mac
• Subsystem:

Possible Solution

adding the feature view name as part of the entity_id or allow for concurrent or/and updates of the same key in case features have the same event_timestamp
