when did the processes of the couchjs launch by the beam process(couchdb)？

[mudanzha]

i installed couchdb in 3 different VM, and make them into a cluster using Haproxy as a proxy agent。But the processes of their are different. Two of their did not launch couchjs process and the last one launched in the next day. i can not understand when the couchjs launched by couchdb_beam, and please tell me how to launch couchjs processes.

couchjs processes are launched as needed by CouchDB for processing JavaScript.

You can adjust parameters of how these processes are launched via settings in your local.ini file. You want the settings under the [query_server_config] section. Here's our documentation on those settings.
