在mongodb2.6以后 使用  Bulk()

[db.collection.initializeOrderedBulkOp()][db.collection.initializeOrderedBulkOp] or the[db.collection.initializeUnorderedBulkOp()][db.collection.initializeUnorderedBulkOp] method.

得到bulk

如果有一个失败，剩余的会终止，执行是顺序执行的

详细:https://docs.mongodb.org/manual/reference/method/db.collection.initializeOrderedBulkOp/\#db.collection.initializeOrderedBulkOp

[db.collection.initializeUnorderedBulkOp()][db.collection.initializeUnorderedBulkOp]:

https://docs.mongodb.org/manual/reference/method/db.collection.initializeUnorderedBulkOp/\#db.collection.initializeUnorderedBulkOp

Each group of operations can have at most [1000 operations][1000_operations]. If a group exceeds this [limit][1000_operations], MongoDB will divide the group into smaller groups of 1000 or less. For example, if the bulk operations list consists of 2000 insert operations, MongoDB creates 2 groups, each with 1000 operations.

如果操作过多，会切分成1000个操作
