Can this skill modify my MongoDB data?

No, this skill operates strictly in read-only mode to ensure data safety and integrity while exploring or querying your database.

How does this skill help with large datasets?

It provides specific patterns like the Bucket and Subset patterns to handle time-series data and prevent documents from exceeding the 16MB limit.

What is the ESR rule mentioned in the skill?

The ESR (Equality, Sort, Range) rule is a best practice for ordering fields in compound indexes to achieve maximum query performance.

Can it help write aggregation queries?

Yes, it provides optimized templates for $match, $project, $group, and $lookup stages to ensure efficient data processing without performance hits.

Does it support MongoDB Atlas?

Yes, it includes connection string best practices for MongoDB Atlas, local instances, and replica sets.
