BLOB storage

Documentation says eventually large binary objects would be stored as files.
Does anyone have more details on this?
How large is that?
How and where is that stored locally?
How is that stored on the server if I sync? Is it stored as a file as well?

Thanks for any info.

We’re working on our documentation regarding binary data, which are referenced as Attachments to JSON documents (see: Locally, this data is stored in the file system and there is no cap set out by Couchbase Lite. However, there is a cap on Couchbase Server–I believe it is 20MB.
