# PutMongoBulkOperation

## Description:

This processor runs bulk updates against MongoDB collections. The flowfile content is expected to be a JSON array with
bulk write operations as described in
the [manual for db.collection.bulkWrite](https://www.mongodb.com/docs/manual/reference/method/db.collection.bulkWrite/).

You can use all (currently 6) operators described there. The flowfile content is returned as-is. You can merge many
operations into one - and get massive performance improvements.

## Example:

The following is an example flowfile content that does two things: insert a new document, and update all documents where
value of _hey_ is greater than zero.

```json
[
  {
    "insertOne": {
      "document": {
        "ho": 42
      }
    }
  },
  {
    "updateMany": {
      "filter": {
        "hey": {
          "$gt": 0
        }
      },
      "update": {
        "$inc": {
          "hey": 2
        }
      }
    }
  }
]
```
