MongoDB\Driver\Manager::executeBulkWrite — Execute one or more write operations

### Description

final public MongoDB\Driver\Manager::executeBulkWrite(string `$namespace`, MongoDB\Driver\BulkWrite `$bulk`, array|MongoDB\Driver\WriteConcern|null `$options` = `null`): MongoDB\Driver\WriteResult

Executes one or more write operations on the primary server.

A MongoDB\Driver\BulkWrite can be constructed with one or more write operations of varying types (e.g. updates, deletes, and inserts). The driver will attempt to send operations of the same type to the server in as few requests as possible to optimize round trips.

The default value for the `"writeConcern"` option will be inferred from an active transaction (indicated by the `"session"` option), followed by the connection URI.

### Parameters

`namespace` (string)

  A fully qualified namespace (e.g. `"databaseName.collectionName"`).

`bulk` (MongoDB\Driver\BulkWrite)

  The write(s) to execute.

`options`

  options
  Option | Type | Description
  --- | --- | ---
  session | MongoDB\Driver\Session | A session to associate with the operation.
  writeConcern | MongoDB\Driver\WriteConcern | A write concern to apply to the operation.

### Return Values

Returns MongoDB\Driver\WriteResult on success.

### Errors/Exceptions

- Throws MongoDB\Driver\Exception\InvalidArgumentException if `bulk` does not contain any write operations.
- Throws MongoDB\Driver\Exception\InvalidArgumentException if `bulk` has already been executed. MongoDB\Driver\BulkWrite objects may not be executed multiple times.
- Throws MongoDB\Driver\Exception\InvalidArgumentException if the `"session"` option is used in combination with an unacknowledged write concern.
- Throws MongoDB\Driver\Exception\InvalidArgumentException on argument parsing errors.
- Throws MongoDB\Driver\Exception\ConnectionException if connection to the server fails (for reasons other than authentication).
- Throws MongoDB\Driver\Exception\AuthenticationException if authentication is needed and fails.
- Throws MongoDB\Driver\Exception\BulkWriteException on any write failure (e.g. write error, failure to apply a write concern)
- Throws MongoDB\Driver\Exception\RuntimeException on other errors.

### Changelog

Version | Description
--- | ---
PECL mongodb 1.4.4 | MongoDB\Driver\Exception\InvalidArgumentException will be thrown if the `"session"` option is used in combination with an unacknowledged write concern.
PECL mongodb 1.4.0 | The third parameter is now an `options` array. For backwards compatibility, this paramater will still accept a MongoDB\Driver\WriteConcern object.
PECL mongodb 1.3.0 | MongoDB\Driver\Exception\InvalidArgumentException is now thrown if `bulk` does not contain any write operations. Previously, a MongoDB\Driver\Exception\BulkWriteException was thrown.

### Examples

Example #1 MongoDB\Driver\Manager::executeBulkWrite() example

    <?php

    $bulk = new MongoDB\Driver\BulkWrite();

    $bulk->insert(['_id' => 1, 'x' => 1]);
    $bulk->insert(['_id' => 2, 'x' => 2]);

    $bulk->update(['x' => 2], ['$set' => ['x' => 1]], ['multi' => false, 'upsert' => false]);
    $bulk->update(['x' => 3], ['$set' => ['x' => 3]], ['multi' => false, 'upsert' => true]);
    $bulk->update(['_id' => 3], ['$set' => ['x' => 3]], ['multi' => false, 'upsert' => true]);

    $bulk->insert(['_id' => 4, 'x' => 2]);

    $bulk->delete(['x' => 1], ['limit' => 1]);

    $manager = new MongoDB\Driver\Manager('mongodb://localhost:27017');
    $writeConcern = new MongoDB\Driver\WriteConcern(MongoDB\Driver\WriteConcern::MAJORITY, 100);
    $result = $manager->executeBulkWrite('db.collection', $bulk, $writeConcern);

    printf("Inserted %d document(s)\n", $result->getInsertedCount());
    printf("Matched  %d document(s)\n", $result->getMatchedCount());
    printf("Updated  %d document(s)\n", $result->getModifiedCount());
    printf("Upserted %d document(s)\n", $result->getUpsertedCount());
    printf("Deleted  %d document(s)\n", $result->getDeletedCount());

    foreach ($result->getUpsertedIds() as $index => $id) {
        printf('upsertedId[%d]: ', $index);
        var_dump($id);
    }

    /* If the WriteConcern could not be fulfilled */
    if ($writeConcernError = $result->getWriteConcernError()) {
        printf("%s (%d): %s\n", $writeConcernError->getMessage(), $writeConcernError->getCode(), var_export($writeConcernError->getInfo(), true));
    }

    /* If a write could not happen at all */
    foreach ($result->getWriteErrors() as $writeError) {
        printf("Operation#%d: %s (%d)\n", $writeError->getIndex(), $writeError->getMessage(), $writeError->getCode());
    }
    ?>

The above example will output something similar to:

    Inserted 3 document(s)
    Matched  1 document(s)
    Updated  1 document(s)
    Upserted 2 document(s)
    Deleted  1 document(s)
    upsertedId[3]: object(MongoDB\BSON\ObjectId)#5 (1) {
      ["oid"]=>
      string(24) "54d3adc3ce7a792f4d703756"
    }
    upsertedId[4]: int(3)
