Missing index on key property on Mongodb

[gkampitakis]

I created an issue to the original repository just in case someone has the same issue. What was noticed is that the library creates an index

node_acl/lib/mongodb-backend.js

Line 145 in 966d079

collection.createIndex({ _bucketname: 1, key: 1 }, (err) => {

and then in the case of the useSingle=false we are not using this index as we are querying with just the key meaning we are not using the index resulting to slow queries. Maybe the index could respect the useSingle flag and create the correct index.

node_acl/lib/mongodb-backend.js

Line 121 in 966d079

var updateParams = this.useSingle ? { _bucketname: bucket, key: key } : { key: key };
