IDBObjectStore.getAll()

[oliverlj]

It is possible to add method IDBObjectStore.getAll() which is faster than open a cursor ?

Thanks

Hey @oliverlj, thanks for opening. I’m open to adding that method on the object store since it’s in the spec. If you’d like, you’re welcome to create a PR for it.

I don’t have much experience with the performance of getAll(), though I’d be surprised if the cursor were noticeably slower. Cursors are supposed to make large accesses a bit more efficient so that’s interesting. 🤔 Out of curiosity, do you have an article or something I could read up on?

I found the performance information in this article :

yep, I can try to do a PR for this

That's a great article, thank you for sharing. For whatever reason, this one didn't come up in my early research on this topic. Definitely bookmarking 🙂

Thanks for giving it a shot. I suspect we'll need to add 2 new methods to *baseObjectStore so it is picked up by both *Index and *ObjectStore. If modeling them after the key-only versions, then it might look like GetAll() and GetAllRange(*KeyRange, uint).
