> Hello,
> To improve write performance, we need support for bulk operations :
> [https://mongodb.github.io/mongo-java-driver/3.6/driver/tutorials/bulk-writes/]
>  [https://docs.mongodb.com/manual/core/bulk-write-operations/]
> I will add new bulkWrite operation that expect a list of WriteModel Object in body.
> Example :
> {code:java}
> // route: from("direct:bulkWrite").to("mongodb:myDb?database=science&collection=notableScientists&operation=bulkWrite");
> List<WriteModel<DBObject>> bulkOperations = Arrays.asList(
>                 new InsertOneModel<>(new BasicDBObject("scientist", "Descartes")),
>                 new InsertOneModel<>(new BasicDBObject("scientist", "Pierre Curie")),
>                 new UpdateOneModel<>(new BasicDBObject("_id", "5"), new BasicDBObject("$set", new BasicDBObject("scientist", "Marie Curie"))),
>                 new DeleteOneModel<>(new BasicDBObject("_id", "2")));
> BulkWriteResult result = template.requestBody("direct:bulkWrite", bulkOperations, BulkWriteResult.class);
> {code}
>       
> An header with key CamelMongoDbBulkOrdered will be added (true is the default value).
> {code:java}
> BulkWriteResult result = template.requestBodyAndHeader("direct:bulkWrite", bulkOperations, MongoDbConstants.BULK_ORDERED, false, BulkWriteResult.class)
> {code}
> Later, i will add support for String :
> {code:java}
> // route: from("direct:bulk").to("mongodb:myDb?database=science&collection=notableScientists&operation=bulkWrite");
> template.requestBody("direct:bulkWrite", "[
>  { \"insertOne\" : { \"document\" : { \"scientist\" : \"Descartes\" }}},
>  { \"insertOne\" : { \"document\" : { \"scientist\" : \"Pierre Curie\" }}},
>  { \"updateOne\" : { \"filter\" : { \"_id\" :  \"5\" }, \"update\" : { \"$set\" : { \"scientist\" : \"Marie Curie\" }}}},
>  { \"deleteOne\" : { \"filter\" : { \"_id\" : 2} }} ]");
> {code}
> I will do 2 PR.
