Set metadata config in Pinecone dashboard
One of the beauties of reading the documentation is finding everything you didn’t know you can do, even after some time of using a product (because you never rtfm straight away ofc).
When creating an index, the “wizard” needs an upload .json config option under “Advanced configuration”. Upload, validate, create, done.
Maybe even the same option (modify metadata config) under “Configure” on a created Index wouldn’t be that bad. Of course with that option the user should be notified in red and blinking lights that the index will be turned into a collection, terminated and then recreated with the same settings as before but with modified metadata config.
For a start the option on create index would be fine for the majority of users (metadata config probably isn’t used that much anyway?).
