note 124281 added to mongodb-driver-bulkwrite.insert

Here is a question about bulk insert. Right after $bulk->insert, i see an MongoDB\BSON\ObjectId retrieved instantly. So how to ensure the ObjectId’s uniqueness? Is bulk_write asking for and ObjectId every time? ---- Server IP: 208.43.231.9 Probable Submitter: 185.85.3.195 (proxied: 124.202.169.82) ---- Manual Page -- http://php.net/manual/en/mongodb-driver-bulkwrite.insert.php Edit -- https://master.php.net/note/edit/124281 Del: integrated -- https://master.php.net/note/delete/124281/integrated Del: useless -- https://master.php.net/note/delete/124281/useless Del: bad code -- https://master.php.net/note/delete/124281/bad+code Del: spam -- https://master.php.net/note/delete/124281/spam Del: non-english -- https://master.php.net/note/delete/124281/non-english Del: in docs -- https://master.php.net/note/delete/124281/in+docs Del: other reasons-- https://master.php.net/note/delete/124281 Reject -- https://master.php.net/note/reject/124281 Search -- https://master.php.net/manage/user-notes.php
