"uncap" limited collection of MongoDB

Question

Is there a way to “smash” a limited collection? Creating a new collection and copying data is not an option for me.

thanks

Answer 1

No. You can convert a non-capped collection to a limited collection using the "convertToCapped" command, but there is no way to go the other way.

Your only option is to clone the collection into unlimited and rename it, which, obviously, is associated with downtime.

Answer 2

Unfortunately, the only option here is to copy the collection, delete the old one and rename the new one:

$> db.collection_name.copyTo('collection_name2') $> db.collection_name.isCapped() true $> db.collection_name.drop() $> db.collection_name2.renameCollection('collection_name') $> db.collection_name.isCapped() false
