spring数据是否使用新的MongoDB Bulk API进行批量操作？

Question

see http://docs.mongodb.org/manual/reference/method/Bulk/

Can you please point me to the version which supports this new API or in which version this support will be available?

Answer 1

There's currently no dedicated support for the bulk operations introduced in MongoDB 2.6. If you think these operations are worthwhile to add support for, please raise a ticket in out JIRA .

In the meantime you can use a CollectionCallback to execute bulk operations on the raw MongoDB collection:

template.execute(new CollectionCallback<Void> {

    Void doInCollection(DBCollection collection) {

        BulkWriteOperation operation = collection.initialize(Uno|O)rderedBulkOperation();
        // bulk code goes here
        operation.execute();
        return null;
    }
}

Answer 2

MongoDB Java Driver for MongoDB v2.6 does support bulk operations however since these are very new set of operations which were not provided in MongoDB v2.4, these may not have made into stable versions of Spring Data yet. I see there are planned 1.5.X SpringData but don't see any associated API / reference for these yet on their website.
