Bulk Write - Part 1

What is bulkWrite?

MongoDB provides a bulkWrite function to perform write-operations in bulk. In a write-operation, we individually perform create, update and delete operations… Instead, we can use the bulkWrite function to perform all these operations together.

bulkWrite command syntax

Syntax of the bulkWrite function:

db.<collection-name>.bulkWrite(
   [ <operation 1>, <operation 2>, ... ],
   {
      writeConcern : <document>,
      ordered : <boolean>
   }
)

The first argument is an array of operations. The bulkWrite method can execute multiple operations through one command, including create, update or delete operation.
