Hi! Jocelyn here. We’ve noticed that how to retrieve IDs is a popular question. Pinecone teammate @jesse made a great response here I’m dropping a few pointers below to reduce zombie threads:
In a nutshell, this can be achieve by using the list operation to get the IDs of records in an index namespace. You can get the IDs of all records in a namespace or just the records with a common ID prefix.
As always, the docs are your source of truth - but feel free to discuss your project here, or ask clarifying questions. We’ll do our best to lend a hand!
