Can the "Aggregations" tab in MongoDB Compass alter original documents?
Is there a risk of unintended modification to original documents when using the "Aggregations" tab in MongoDB Compass? I want to ensure that my data remains unchanged and intact throughout the aggregation process.
MongoDB Compass for Mac, version 1.38.0
Solution
According to official docs it says:
Aggregation pipelines run with the
db.collection.aggregate()method do not modify documents in a collection, unless the pipeline contains a$mergeor$outstage.
Also since MongoDB 4.2 you can use aggregations pipeline into update queries, but that's not the point.
