Thanks for pointing that out! View all posts by Laks. Looking for some examples? Because topics are just concepts, their implementation and routing behavior is decided by specific brokers. None. That's a typo... "shared" --> "sharded". Synchronous replication is not supported. This promotes a loosely-coupled architecture, and provides a scalable, one-to-many style of communication. For an in-depth comparison, watch my full video below. It can be thought of as a property of a message, or metadata, and not like “writing to a file” or “sending to a destination.” Each and every message could be published with a unique topic. WSO2 OpenSource contributor, API M, IS, EI and Mule Offers high performance for simple pub/sub, struggles to support features that require knowledge of state or changes to published message format. Hans Jespersen is a principal systems engineer at Confluent where he helps other organizations get maximum value from Apache Kafka and the Confluent platform. Looking to dive deeper into the details?

Wide variety of lightweight standard APIs (JMS, JCA) and proprietary APIs for server, web and. But the real differences are in how topics are implemented in the two brokers.
Ever wondered what the difference is between a Solace topic and an Apache Kafka topic?

Sr Architect @ Appirio And the limit bit is an oversimplification of the issue with two open file handles for every topic partition file, which does limit the total number of topics in Kafka. Solace Topics vs. Kafka Topics: What’s the Difference. Anything else I misrepresented? But since published topics are so dynamic, how do we manage this from a subscription perspective? Think of a topic as a concept of the publish-subscribe (pub/sub) architectural pattern. "Messages on Kafka topics are shared across partitions, and this can result in out-of-order messages across the whole topic, and can put a limit on the number of topics you can maintain in a Kafka broker.".
Solace supports backward compatibility of all APIs and between Solace brokers. Kafka vs Solace - Type 2 keywords and click on the 'Fight !'
Now, from an API perspective, Kafka and Solace APIs look pretty similar at first glance—both can subscribe and publish to a topic. I'll fix up the blog. Press question mark to learn the rest of the keyboard shortcuts. All capabilities deployed as one executable in the VMR or in the appliance. Offers high performance for simple pub/sub, struggles to support features that require knowledge of state or changes to published message format. Solace supports both multi-level > and single-level * prefix wildcards. The differences between Solace PubSub+ and Kafka in terms of architecture, message handling, security and operations It also gives us the option to perform stateful stream processing by defining the underlying topology. The short answer is… quite a lot. Solace supports both multi-level > and single-level * prefix wildcards. Definitely check out the whole video, and then connect with me here on LinkedIn if you have additional questions. Kafka comes to the rescue here, both microservices can share a Kafka topic and use it to achieve eventual consistency. MQTT, REST, Websockets, COMET supported by the broker along with interoperability between them – no proxies required. appeared first on Solace. ( Log Out / ( Log Out /
The answer: subscription wildcards. The writer clearly doesn't understand Kafka topics at all. KAFKA PECULIARITIES.

Consumers only get the messages that they’ve subscribed to, versus having to filter at the receiving end. With Solace, topics aren’t actually configured on the broker. "Messages on Kafka topics are shared across partitions, and this can result in out-of-order messages across the whole topic, and can put a limit on the number of topics you can maintain in a Kafka broker." applications. Kafka Streams, a part of the Apache Kafka project, is a client library built for Kafka to allow us to process our event data in real time. Start small. Requires external gateways for REST; MQTT/AMQP likely not possible due to lack of message routing capabilities. They’re instead defined by the publishing application at publish time.
Take a look at some examples at 7:20: Solace’s hierarchical topic structure (multiple levels, delimited by slash /) and wildcard ability allows for much more fine-grained filtering at the broker than you may be able to get with a Kafka broker.

Because of this, there’s a strong order guarantee on topics in Solace; if two clients/consumers are subscribed to the same topics, they will always receive messages in the exact same order. You can’t subscribe to an infinite number of topics! The post Solace Topics vs. Kafka Topics: What’s the Difference? Solace Topics vs. Kafka Topics: Whats the Difference? Broker available as hardware appliance or software – functionally equivalent. Sophisticated broker aware of all publishers, subscribers, queue and message state.
They are used to route data or events (in the form of messages) between distributed applications, often using a message broker or an event broker. All APIs supported and frequently updated by Solace. You have decided to have two microservices to update customer data, one for sales and another for claims, you have done this because of although, they will update the same customer, the data is different. Messages on topics are striped across partitions, and this can result in out-of-order messages, and can put a limit on the number of topics you can maintain in a Kafka broker.

Before coming to Confluent, Hans worked as the vice president of systems engineering at Solace Systems after spending many years contributing to the success of other companies. Kafka topics are implemented as log files, and because of this file-based topic system, topics in Kafka are a very “broker-centric” concept. Solace forwards the message onto the clients on a message-by-message basis as they arrive at the broker, using essentially a subscription matching engine. Built-in via bridging and multi-node dynamic routing. Press J to jump to the feed.

The writer clearly doesn't understand Kafka topics at all. Proprietary, thick API makes consumer responsible for consumer state, connectivity to many brokers, finding partition leaders. Whenever a publisher or producer sends a message on that topic, the broker forwards the message to any consumers that have a matching topic subscription. Discussion of the Apache Kafka distributed pub/sub system. Typically, consuming applications register a topic subscription of interest with the broker. Requires 3x (dedicated) Zookeeper to store configuration data and message state. Change ).
