couchdb Max_document_size

Question

We are going to use bigcouch to serve images. The max image size is ~5MB. The config value is at 64MB. Should we change it to somewhere close? What is the reason behind it?

Thanks,

Kathleen

Answer 1

You should not change it. I'm pretty sure that value is excluding attachments.

The max document size is just for the JSON part of the document (not your image attachments), and it prevents the server from using too much memory to hold an oversized document.

Also, you may ignore @ajreal, he seems to have no idea what he is saying.

Answer 2

Assuming you stream the attachment in as standalone (i.e, PUT /dbname/docid/attachment_name) you won't hit the max_document_size limit. Jason is correct that it only limits the size of a JSON body PUT. I also second his opinion that ajreal is talking crap.
