Kafka Topic

Overview

Apache Kafka is an end-to-end event streaming platform that:

• Publishes (writes) and subscribes to (reads) streams of events from sources like databases, cloud services, and software applications.

• Stores these events durably and reliably for as long as you want.

• Processes and reacts to the event streams in real-time and retrospectively.

Those events are organized and stored in topics. These topics are then partitioned over buckets located on different Kafka brokers.

Event streaming thus ensures a continuous flow and interpretation of data so that the right information is at the right place, at the right time for your key use cases.

Before you set up your data sync destination, make sure to configure your Source.

The Kafka Topic destination supports batch and real-time syncs.

Destination tab

The following table outlines the mandatory and optional parameters you will find on the Destination tab (Image 1).

Destination Details

The following parameters will help to define your data sync destination and how it functions.

Parameter	Description	Example
Destination	Mandatory. Select your destination from the drop down menu.	Kafka Topic
Bootstrap Servers	Mandatory. Bootstrap Servers are a list of host/port pairs to use for establishing the initial connection to the Kafka cluster. This parameter should a CSV list of "broker host" or "host:port"	localhost:9092,another.host:9092
Topic Name	Mandatory. The name of the Kafka Topic that messages will be produced to.
Use SSL	Check this if you want to connect to Kafka over SSL
SASL Mechanism	Mandatory. Select the SASL (Simple Authentication and Security Layer) Mechanism to use for authentication:- None- PLAIN- SCRAM-SHA-256- SCRAM-SHA-512- OATHBEARER (default)- OATHBEARER (OIDC)
Test Connection	You can use the "Test Connection" button to ensure that your credentials are properly configured to access your destination. If configured correctly, a "Connection Successful" pop-up will appear. If configured incorrectly, a "Connection Failed" pop-up will appear along with a link to the applicable error logs to help you troubleshoot.

Column Mapping

The Column Mapping section is where you define which source columns you want to sync to which destination columns. You can repeat the values for multiple columns.

The names you specify in your "Target Column" value will turn into attributes in a JSON payload that will be constructed and pushed to Kafka. The name of this target column can be whatever you choose, but we recommend maintaining your naming convention across columns for simplicity.

Parameter	Description	Example
Source Column	Mandatory. The name of your column as it appears in the source.	Name
Target Column	Mandatory. The name of your column as it appears in the destination.	Name

Next steps

• Define your Sync Actions.

• Add in your Post Sync Scripts, if required.

• Define your Permissions.

• If you are running a real-time sync, set up your Listener Config and enable it to begin your sync.

• If you are running a batch sync, click Jobs > Start a Job to begin your sync.
