# Introduction

Kafka Connect is a tool for streaming data between Apache Kafka and other
systems without writing a single line of code. Via Kafka Sink Connectors, you
can export your data into any other storage. Via Kafka Source Connectors, you
can pull data to your Kafka topics from other systems.

Kafka Connectors can be self hosted but it requires you to setup and maintain
extra processes/machines. Upstash provides hosted versions of connectors for
your Kafka cluster. This will remove the burden of maintaining an extra system and also improve performance, as it will be closer to your cluster.

## Pricing

Connectors are **free** to use. We don't charge anything extra for connectors
other than per message pricing of Kafka topics. Check out
[Pricing](https://upstash.com/pricing/kafka) for details on our per message pricing.

## Get Started

We will create a MongoDB source connector as an example. You can find examples
for all supported connectors on the left side bar under `Connectors` section.

### Create a Kafka Cluster

<Info>
  If you do not have a Kafka cluster and/or topic already, follow [these
  steps](../overall/getstarted) to create one.
</Info>

### Create a MongoDB Database

Let's prepare our MongoDB Atlas Database. Go to
[MongoDB Atlas](https://www.mongodb.com/cloud/atlas/register) and register.
Select `Build Database` and choose the `Free Shared` option for this example.
Proceed with `Create Cluster` as the defaults should be fine. If this is
your first time, you will see `Security Quickstart` screen.

Choose a username and password. You will need these later to put it in
connection string to MongoDB.

</Frame>

<Warning>
  You will be allowing Upstash to connect to your MongoDB database in the next
  screen. So be careful in this step.
</Warning>

Select Cloud Environment and then IP Access List. Enter following static Upstash
IP addresses to IP Access List.

```
52.48.149.7
52.213.40.91
174.129.75.41
34.195.190.47
52.58.175.235
18.158.44.120
63.34.151.162
54.247.137.96
3.78.151.126
3.124.80.204
34.236.200.33
44.195.74.73
```

</Frame>

From here, you will be redirected to Database Deployments screen. Go to
`Connect` and select `Connect your application` to find the MongoDB
URI(connection string). Copy this string to use later when creating our Kafka
Connector. Don't forget to replace the password that you selected earlier for
your MongoDB user.

### Create the Connector

Head over to [console.upstash.com](https://console.upstash.com) and select
your Kafka cluster. Go the Connectors tab, and create your first connector with
`New Connector` button.

<Frame>
  <img src="https://mintlify.s3-us-west-1.amazonaws.com/upstash-vector/img/kafka/connect/connector.png" width="100%" />
</Frame>

Then choose your connector as `MongoDB Connector Source` for this example.

<Frame>
  <img src="https://mintlify.s3-us-west-1.amazonaws.com/upstash-vector/img/kafka/connect/mongo/source/1connector.png" />
</Frame>

Choose a connector name and enter MongoDB URI(connection string) that we
prepared earlier in Config screen. Other configrations are optional. We will
skip them for now.

<Frame>
  <img src="https://mintlify.s3-us-west-1.amazonaws.com/upstash-vector/img/kafka/connect/mongo/source/2config.png" />
</Frame>

Advanced screen is for any other configuration that selected Connector supports.
At the top of this screen, you can find a link to related documentation. For
this example, we can proceed with what we have and click `Connect` button
directly.

</Frame>

Congratulations you have created your first source connector to Kafka. Note that
no topics will be created until some data is available on the MongoDB.

### See It In Action

With this setup, anything that you have introduced in your MongoDB will be
available on your Kafka topic immediately.

Lets go to MongoDB and populate it with some data.

From main `Database` screeen, choose `Browse Collections` , and then click
`Add My Own Data`. Create your database in the next screen.

Select `Insert Document` on the right.

<Frame>
  <img src="https://mintlify.s3-us-west-1.amazonaws.com/upstash-vector/img/kafka/connect/mongo/source/insert1.png" width="100%" />
</Frame>

And lets put some data here.

<Frame>
  <img src="https://mintlify.s3-us-west-1.amazonaws.com/upstash-vector/img/kafka/connect/mongo/source/insert2.png" />
</Frame>

Shortly, we should see a topic created in Upstash Console Kafka with
`DATABASE_NAME.COLLECTION_NAME` in MongoDB database.

<Frame>
  <img src="https://mintlify.s3-us-west-1.amazonaws.com/upstash-vector/img/kafka/connect/mongo/source/topic.png" width="100%" />
</Frame>

After selecting the topic, you can go to `Messages` section to see latest events
as they are coming from Kafka.
