[Confluent Cloud](https://www.confluent.io/confluent-cloud/?utm_campaign=tm.pmm_cd.cwc_partner_Qdrant_generic&utm_source=Qdrant&utm_medium=partnerref) is a fully-managed data streaming platform, available on AWS, GCP, and Azure, with a cloud-native Apache Kafka engine for elastic scaling, enterprise-grade security, stream processing, and governance.

With our [Qdrant-Kafka Sink Connector](https://github.com/qdrant/qdrant-kafka), Qdrant is part of the [Connect with Confluent](https://www.confluent.io/partners/connect/) technology partner program. It brings fully managed data streams directly to organizations through the Confluent Cloud platform. Making it easier for organizations to stream any data to Qdrant with a fully managed Apache Kafka service.

## Usage

### Pre-requisites

- A Confluent Cloud account. You can begin with a [free trial](https://www.confluent.io/confluent-cloud/tryfree/?utm_campaign=tm.pmm_cd.cwc_partner_qdrant_tryfree&utm_source=qdrant&utm_medium=partnerref) with credits for the first 30 days.
- Qdrant instance to connect to. You can get a free cloud instance at [cloud.qdrant.io](https://cloud.qdrant.io/).

### Installation

1) Download the latest connector zip file from [Confluent Hub](https://www.confluent.io/hub/qdrant/qdrant-kafka).

2) Configure an environment and cluster on Confluent and create a topic to produce messages for.

3) Navigate to the `Connectors` section of the Confluent cluster and click `Add Plugin`. Upload the zip file with the following info.
