What are the limits regarding the max size of value and number of keys? Docs doesn't mention...

It’s at the very end of the blog post:

“The maximum size of a key value store is 5 MB, and you can associate a single key value store to each function. The maximum size of a key is 512 bytes. Values can be up to 1KB in size.“

Thanks, should've grepped for "max". But the amount of keys wasn't mentioned.
