online and offline store clarification

[theprofessorvijay]

Hello,

I understand that core service is used for registering the metadata about features, I am not clear about what is the role of serving in Feast,
for example I have created feast client as below, my core is connected to PostgreSQL and serving is connected to Redis

client = Client(core_url='localhost:6565', serving_url='localhost:6566', project="demo")

While getting FeatureStore why is that we need to specify online and offline store configuration details like redis connection string, is not supposed to connect to Redis thorough serving URL for loading the data for online serving? similarly we have provided batch_source while creating FeatureTable, is not enough to get the data for offline training (historical data)?

In a production environment, sharing Redis credentials not an option to create FeatureStore

Please clarify

Note: I have gone through the documentation, still do not have clarity

@theprofessorvijay Can you please use the latest version of Feast? Feast 0.9 is not supported any more.
