Correct way to implement cart management in medusa

[Labham-Jain]

Hey there,

I'm currently working on implementing a cart feature for an ecommerce platform and could use some guidance on where to store the cart ID for each user. Currently, I've chosen to place the cart ID in the customer's metadata field. However, I'm not entirely sure if this is considered a good practice or if there might be better alternatives available.

To get things started, I have a few questions:

Is storing the cart ID in the customer's metadata field a recommended practice?
Are there any potential drawbacks or limitations to this approach?
Have you encountered any successful alternative storage locations for cart IDs in similar projects?
Are there any security or performance considerations associated with different storage options?
