Executes multiple write operations.

function bulkWrite(
array $operations,
array $options = []
): MongoDB\BulkWriteResult
$operations : array

An array containing the write operations to perform. MongoDB\Collection::bulkWrite() supports MongoDB\Collection::deleteMany(), MongoDB\Collection::deleteOne(), MongoDB\Collection::insertOne(), MongoDB\Collection::replaceOne(), MongoDB\Collection::updateMany(), and MongoDB\Collection::updateOne() operations in the following array structure:

[ 'deleteMany' => [ $filter ] ],
[ 'deleteOne' => [ $filter ] ],
[ 'insertOne' => [ $document ] ],
[ 'replaceOne' => [ $filter, $replacement, $options ] ],
[ 'updateMany' => [ $filter, $update, $options ] ],
[ 'updateOne' => [ $filter, $update, $options ] ],

Arguments correspond to the respective operation methods. However, the writeConcern option is specified as a top-level option to MongoDB\Collection::bulkWrite() instead of each individual operation.

$options : array

An array specifying the desired options.

If true, allows the write operation to circumvent document level validation. Defaults to false.

The codec to use for encoding or decoding documents. This option is mutually exclusive with the typeMap option.

Defaults to the collection's codec. Inheritance for a default codec option takes precedence over that of the typeMap option.

Bulk writes use the codec for insertOne and replaceOne operations.

New in version 1.17.


Enables users to specify an arbitrary comment to help trace the operation through the database profiler, currentOp output, and logs.

This option is available since MongoDB 4.4 and will result in an exception at execution time if specified for an older server version.

New in version 1.13.


Map of parameter names and values. Values must be constant or closed expressions that do not reference document fields. Parameters can then be accessed as variables in an aggregate expression context (e.g. $$var).

This is not supported for server versions prior to 5.0 and will result in an exception at execution time if used.

New in version 1.13.


If true: when a single write fails, the operation will stop without performing the remaining writes and throw an exception.

If false: when a single write fails, the operation will continue with the remaining writes, if any, and throw an exception.

The default is true.


Client session to associate with the operation.

New in version 1.3.


Write concern to use for the operation. Defaults to the collection's write concern.

It is not possible to specify a write concern for individual operations as part of a transaction. Instead, set the writeConcern option when starting the transaction.

A MongoDB\BulkWriteResult object, which encapsulates a MongoDB\Driver\WriteResult object.

MongoDB\Exception\UnsupportedException if options are used and not supported by the selected server (e.g. collation, readConcern, writeConcern).

MongoDB\Exception\InvalidArgumentException for errors related to the parsing of parameters or options.

MongoDB\Driver\Exception\BulkWriteException for errors related to the write operation. Users should inspect the value returned by getWriteResult() to determine the nature of the error.

MongoDB\Driver\Exception\RuntimeException for other errors at the driver level (e.g. connection errors).

If a MongoDB\Driver\Exception\BulkWriteException is thrown, users should call getWriteResult() and inspect the returned MongoDB\Driver\WriteResult object to determine the nature of the error.

For example, a write operation may have been successfully applied to the primary server but failed to satisfy the write concern (e.g. replication took too long). Alternatively, a write operation may have failed outright (e.g. unique key violation).

In the case of a bulk write, the result may indicate multiple successful write operations and/or errors. If the ordered option is true, some operations may have succeeded before the first error was encountered and the exception thrown. If the ordered option is false, multiple errors may have been encountered.
