Hey,

Small post outlining a small modification to the 0.4 lightcouch source to allow direct plain text json insertion. A colleague and I had a JSON string which we wanted to insert into lightcouch without having to create a JSON object – only to have .toString() be called during the final POST request.

Killing CouchDB on Ubuntu 10.04

This specific content was written 14 years ago. Please keep this in mind as it may be outdated and not adhering to best-practices.

I Wanted to do some maintenance and move my couchdb data files to another partition but couchdb would not stop when I called the usual stop commands:

1)sudo /etc/init.d/couchdb stop
2)sudo service couchdb stop

Found a lot of posts and out of all of them found this nice tidbit below:

ps -U couchdb -o pid= | xargs kill -9

 

Note: It’s not the best thing to viciously kill a process. I imagine databases usually have shutdown tasks to do, must end with current insertions, etc. I’ll post if I find a bug fix.
