Confirming: No API Guarantee for Filter or Append

Would really appreciate confirmation that createReadStream and createWriteStream make no guarantees relevant for:

1. Appending data to a blob. To append a blob, users have to stream the existing data to a buffer, then stream it back to the store, with whatever's to be appended tacked on at the end.
2. Filtering data in a blob. This requires buffering, too.

Many thanks!

That's correct, the interface only guarantees that you'll get a readable or writable stream corresponding to a key. Implementations can use options to extend this though, for example by passing {append: true} to createWriteStream
