# Stream Connector Version Matrix

This page provides a quick-reference matrix mapping each stream connector to its Maven module, artifact ID, underlying client library version, and consumer factory class.

## Connector matrix

| Stream           | Connector Module  | Maven Artifact                     | Client Library Version                             | Consumer Factory Class                                          | Status                                                 |
| ---------------- | ----------------- | ---------------------------------- | -------------------------------------------------- | --------------------------------------------------------------- | ------------------------------------------------------ |
| Apache Kafka 3.x | `pinot-kafka-3.0` | `org.apache.pinot:pinot-kafka-3.0` | kafka-clients 3.9.2                                | `org.apache.pinot.plugin.stream.kafka30.KafkaConsumerFactory`   | Default, included in binary distribution               |
| Apache Kafka 4.x | `pinot-kafka-4.0` | `org.apache.pinot:pinot-kafka-4.0` | kafka-clients 4.1.1                                | `org.apache.pinot.plugin.stream.kafka40.KafkaConsumerFactory`   | Included in binary distribution                        |
| Amazon Kinesis   | `pinot-kinesis`   | `org.apache.pinot:pinot-kinesis`   | AWS SDK 2.42.16 (`software.amazon.awssdk:kinesis`) | `org.apache.pinot.plugin.stream.kinesis.KinesisConsumerFactory` | Included in binary distribution                        |
| Apache Pulsar    | `pinot-pulsar`    | `org.apache.pinot:pinot-pulsar`    | pulsar-client 4.0.9                                | `org.apache.pinot.plugin.stream.pulsar.PulsarConsumerFactory`   | Optional, enable with `-Dplugins.include=pinot-pulsar` |

{% hint style="info" %}
All version numbers above are from the Pinot `master` branch (1.5.0-SNAPSHOT). Released Pinot versions may ship slightly different client library versions. Check the `pom.xml` of the corresponding module in your Pinot release for the exact version.

## Compatibility notes

### Kafka 3.x connector (`pinot-kafka-3.0`)

* Compatible with Kafka brokers version 2.x and above.
* Uses the Scala-based Kafka library alongside `kafka-clients`.
* This is the recommended connector for most deployments.

### Kafka 4.x connector (`pinot-kafka-4.0`)

* Requires Kafka brokers version 4.0 or above.
* Uses the pure-Java `kafka-clients` library only (no Scala dependency).
* Designed for KRaft-mode Kafka clusters that have removed ZooKeeper.
* Uses Testcontainers for integration testing instead of the embedded Kafka server.

### Amazon Kinesis connector (`pinot-kinesis`)

* Uses AWS SDK v2 (`software.amazon.awssdk`).
* Supports both key-based and IAM role-based authentication.
* Included in the default Pinot distribution.

### Apache Pulsar connector (`pinot-pulsar`)

* Not included in the default binary distribution. Enable with `-Dplugins.include=pinot-pulsar` at startup, or add the plugin JAR to the `plugins` directory.
* Uses the Apache Pulsar client library.
* Supports token-based, OAuth2, and TLS authentication.

## Removed connectors

| Former Module     | Removed In | Migration Path                                                            |
| ----------------- | ---------- | ------------------------------------------------------------------------- |
| `pinot-kafka-0.9` | Pre-1.0    | Migrate to `pinot-kafka-3.0`                                              |
| `pinot-kafka-2.0` | Pre-1.0    | Migrate to `pinot-kafka-3.0` (or `pinot-kafka-4.0` for Kafka 4.x brokers) |

To migrate, update `stream.kafka.consumer.factory.class.name` in your table config from the old class to the new one. No other stream config changes are required.
