Unable to insert large document in couchDB

Question

I am unable to upload large documents in couchDB. I am using Node.js to upload with help of ActiveMQ. Small documents are uploading. I tried to upload a document which is 30 MB, but it failed with the following exception:

The answer is right there on the first line of the error stack

(node:28) UnhandledPromiseRejectionWarning: Error: document_too_large

The default maximum document size for couchDB is 8000000 bytes which is far below 30mb.

FWIW 30mb is a lot of data, are you certain the data shouldn't be an attachment? See this related SO Q/A.
