Aggregation out

Aggregation stage $out allows us to output the result of the aggregation pipeline into a new collection:

db.sightings.aggregate([
	{ $match: { species_common: "Eastern Bluebird" } },
	{ $out: "sightings_2022" },
]);

db.sightings_2022.find({})[
	({
		_id: ObjectId("62cf2f0acfe5bbb25ee815fb"),
		species_common: "Eastern Bluebird",
		species_scientific: "Sialia sialis",
		date: ISODate("2022-01-17T18:24:00.000Z"),
		location: { type: "Point", coordinates: [41, -74] },
	},
