$options
] )Constructs a new ordered (default) or unordered MongoDB\Driver\BulkWrite.
options
( array )
Option | Type | Description | Default |
---|---|---|---|
ordered | bool |
Ordered operations ( TRUE ) are executed serially on the MongoDB
server, while unordered operations ( FALSE ) are sent to the server
in an arbitrary order and may be executed in parallel.
| TRUE |
Example #1 MongoDB\Driver\BulkWrite::__construct() example
<?php
$bulk = new MongoDB \ Driver \ BulkWrite ([ 'ordered' => true ]);
$bulk -> delete ([]);
$bulk -> insert ([ '_id' => 1 , 'x' => 1 ]);
$bulk -> insert ([ '_id' => 2 , 'x' => 2 ]);
$bulk -> update (
[ 'x' => 2 ],
[ '$set' => [ 'x' => 1 ]],
[ 'limit' => 1 , 'upsert' => false ]
);
$bulk -> delete ([ 'x' => 1 ], [ 'limit' => 1 ]);
$bulk -> update (
[ '_id' => 3 ],
[ '$set' => [ 'x' => 3 ]],
[ 'limit' => 1 , 'upsert' => true ]
);
$manager = new MongoDB \ Driver \ Manager ( 'mongodb://localhost:27017' );
$writeConcern = new MongoDB \ Driver \ WriteConcern ( MongoDB \ Driver \ WriteConcern :: MAJORITY , 1000 );
try {
$result = $manager -> executeBulkWrite ( 'db.collection' , $bulk , $writeConcern );
} catch ( MongoDB \ Driver \ Exception \ BulkWriteException $e ) {
$result = $e -> getWriteResult ();
// Check if the write concern could not be fulfilled
if ( $writeConcernError = $result -> getWriteConcernError ()) {
printf ( "%s (%d): %s\n" ,
$writeConcernError -> getMessage (),
$writeConcernError -> getCode (),
var_export ( $writeConcernError -> getInfo (), true )
);
}
// Check if any write operations did not complete at all
foreach ( $result -> getWriteErrors () as $writeError ) {
printf ( "Operation#%d: %s (%d)\n" ,
$writeError -> getIndex (),
$writeError -> getMessage (),
$writeError -> getCode ()
);
}
} catch ( MongoDB \ Driver \ Exception \ Exception $e ) {
printf ( "Other error: %s\n" , $e -> getMessage ());
exit;
}
printf ( "Inserted %d document(s)\n" , $result -> getInsertedCount ());
printf ( "Updated %d document(s)\n" , $result -> getModifiedCount ());
printf ( "Upserted %d document(s)\n" , $result -> getUpsertedCount ());
printf ( "Deleted %d document(s)\n" , $result -> getDeletedCount ());
?>
以上例程会输出:
Inserted 2 document(s) Updated 1 document(s) Upserted 1 document(s) Deleted 1 document(s)
