Feature Request: support additional characters allowed in keys

[jinzishuai]

In comparison with other products,

• MongoDB natively allows a user to write the full kubernetes manifest json into a document, including ., / and -. For example, a very commonly seen label looks like

app.kubernetes.io/managed-by: kustomize

• AWS DocumentDB does not allow .. See AWS Documentation

  Amazon DocumentDB does not support dots “.” in a document field name, for example, db.foo.insert({‘x.1’:1}). Amazon DocumentDB also does not support the $ prefix in field names.

• Currently, AstraDB Data API only supports alphanumeric characters plus _. See document on naming convention

  Can contain uppercase letters A-Z, lowercase letters a-z, numbers 0-9, and underscores (_).

Minimal Request

Given the difficulty of ., we request adding support to at least / and -. We are currently using AWS DocumentDB and have already implemented a transformation for . . Supporting / and - in Data API would make it possible for us to migrate to use AstraDB.

thanks, related to #1120

will reach out to get some more details, we know we need to open this up to almost everything. We will do it to align the field names across both Collections and Tables (the iterop with CQL)
