Mardone Dias I see. Personally in my experience, I've not hit those performance bottlenecks yet (I've used CouchDB to handle a few thousands of documents). And I'd say, it's quite harder fetching by keys. However, if that's the case, a workaround could be running an _all_docs to get a list of all documents (just rev and id, without the full document), save those in state/localstorage and use that as basis for performing queries using the ids for start & end key.

Mardone Dias If it's about pagination, why not use limit&skip rather than start & end key? Do you have any special use case why you have to use keys?

Sure. I might need more context though abdulhakeemmustapha@gmail.com

Thanks Shittu. I didn't know about it, but it seems cool.
