[12:31:16] <dusted> I have a sharded cluster, and I'm wondering.. Would the unordered bulk operation (with .find(id).deleteOne() ) be preferred over a single collection.deleteMany( { id: { $in: idList } } ); or are they totally the same? the deleteMany seems to run faster "on my machine"
[12:31:26] <dusted> I can't test it on the cluster atm
[12:32:11] <dusted> something tells me that the bulk operation ought to be able to split calls and send to shards and secondaries that need it, while the deleteMany with the list would have to send the entire list to everyone, making it less efficient, but I'm not sure if that's true
[13:47:07] <guardian> hello, is it a good or bad idea to use transactions and abort_transaction() to implement a dry run feature for a multi collection update?
