Why are the ready reports stored in MongoDB instead of S3/object storage?

Ready reports are stored in MongoDB, not in S3 or other object storage, because MongoDB provides convenient capabilities for fast searching, filtering, and aggregating data. Unlike object storage, where data is stored as files and accessing them requires downloading the entire object, in MongoDB, you can perform queries based on the content of reports, retrieve only the necessary parts of data, and quickly update documents. This is especially important if reports need to be frequently viewed, analyzed, or combined with other data in real-time.
