This article explores the question of whether there is an equivalent to Kafka Tables on Azure Service Bus.

Kafka Tables are utilized in Kafka for events and state representation, however, there is no direct counterpart entity on Azure Service Bus.

Azure Event Hubs, on the other hand, is the most similar service to Kafka for real-time event processing, although it lacks certain features found in Kafka Tables, such as materialized views.

Some sources suggest employing Azure Storage services in conjunction with Azure Event Hubs or Service Bus as a means to achieve comparable functionality.

It is worth noting that there is presently no fully comparable cloud managed service on Azure that can directly substitute for Kafka.

Nevertheless, GitHub projects within the Azure and .Net stack aim to address similar challenges.

It is important to emphasize that this article is a contribution to the Microsoft Azure Collective and the provided answer is based on the contributor’s knowledge and research, with the understanding that alternative answers are encouraged.

The scope of this question does not exclusively pertain to Apache Kafka, Azure Service Bus, or Azure Service Bus Topics, but rather falls within a collective subcommunity defined by relevant tags and content.

Features of Azure Event Hubs

Azure Event Hubs, while being the closest service to Kafka for real-time event processing on Azure, does not provide the same features as Kafka Tables, such as materialized views.

Azure Event Hubs is a cloud-based event streaming platform that can receive and process large volumes of events in real-time. It offers features like scalable event ingestion, low latency, and high throughput.

However, Azure Event Hubs does not have built-in support for materialized views, which allow for the efficient querying of streaming data.

To achieve similar functionality, some articles suggest using Azure Storage services in combination with Azure Event Hubs or Service Bus. This approach allows for the storage and retrieval of processed event data, which can be used to generate materialized views for analysis and querying purposes.

Comparison to Kafka Tables

When comparing the features of Kafka Tables to other services available, it is evident that there is currently no directly comparable entity on Azure.

While Azure Event Hubs is the closest service to Kafka for real-time event processing, it does not offer the same functionality as Kafka Tables, such as materialized views.

Some articles propose using Azure Storage services in conjunction with Azure Event Hubs or Service Bus to achieve similar results. However, these solutions do not provide the same level of integration and ease of use as Kafka Tables.

It is worth noting that there are GitHub projects attempting to address similar problems on the Azure and .NET stack, but they are not officially supported by Azure as a managed service.

Therefore, at present, there is no cloud-managed service on Azure that directly substitutes Kafka Tables.

Possible Alternatives

One possible alternative to Kafka Tables on Azure is to combine Azure Event Hubs or Service Bus with Azure Storage services for achieving similar functionality.

While Azure Event Hubs and Service Bus provide real-time event processing capabilities, they do not offer the same features as Kafka Tables, such as materialized views.

However, by using Azure Storage services such as Azure Blob Storage or Azure Cosmos DB, developers can store and query the event data in a distributed and scalable manner.

This approach allows for the creation of custom materialized views by processing and aggregating the events stored in Azure Storage.

Although it requires additional development effort compared to the native functionality of Kafka Tables, this combination of services can provide a viable alternative for achieving similar functionality on the Azure platform.
