Change many MongoDB documents efficiently instead of sending one database request after another.
When an application needs to perform many database operations, sending each operation separately can create unnecessary network overhead. MongoDB's bulk operations let you send multiple inserts, updates, replacements, or deletes together.
Bulk writes can improve performance when processing large amounts of data, but you still need to understand how MongoDB handles errors, operation ordering, and partial failures. Choosing between ordered and unordered operations can affect both performance and behavior.
