sleep()¶
Definition¶
Example¶
Consider a low-priority bulk data import script. To avoid impacting other processes, you may suspend the shell after inserting each document, distributing the cost of insertion over a longer period of time.
The following example mongo
script will load a JSON file containing
an array of documents, and save one element every 100 milliseconds.
JSON.parse(cat('users.json')).forEach(function(user) { db.users.save(user); sleep(100); });
