Query Optimization
Aggregation framework has a filter, which filters an array (and returns an array).
I wish there was an equivalent to do a javascript Array.find(), where the filter would return the first match inside of the array
db.test.insert({people: [{name: 'bob', value: 1}, {name: 'fred', value: 2}]});
db.test.aggregate([{$addFields: {
person: {
$find: {
input: '$people',
cond: {$eq: ['$$this.name', 'fred']}
}
},
people: '$$REMOVE'
}}]);
##returns
{person: {name: 'fred', value: 2}}
