Workspaces are supported only for file system based storage plugins (DFS, S3).
You can create tables in workspaces, by configuring workspaces as writable. 
Table can be created as file(s) of type parquet, json, psv, csv and tsv, based 
on configuration option “store.format".
For Mongo, creating table is not supported.
