MongoDB documentation should clearly explain how schema validation affects write operations, including bulkWrite, insertOne, insertMany, updateOne, and updateMany. Key improvements:

Performance Impact – Detail validation overhead on write latency.
Validation Scope – Specify when validation is triggered during writes.

This will help developers optimize write operations while using schema validation effectively.

Current solution:
Schema validation requires MongoDB to check documents before committing writes—this inherently introduces some processing overhead.
Bulk operations validate each document in the batch, which could impact performance depending on the complexity of validation rules.
Updates (updateOne/updateMany) validate only modified documents, which generally results in a lower impact.
