We performed a comparison between Apache Kafka and PubSub+ Event Broker based on real PeerSpot user reviews.
Find out in this report how the two Message Queue (MQ) Software solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."The most valuable features of the solution revolve around areas like the latency part, where the tool offers very little latency and the sequencing part."
"It is a stable solution...A lot of my experience indicates that Apache Kafka is scalable."
"The most valuable feature is the messaging function and reliability."
"The use of Kafka's logging mechanism has been extremely beneficial for us, as it allows us to sequence messages, track pointers, and manage memory without having to create multiple copies."
"As a software developer, I have found Apache Kafka's support to be the most valuable...The solution is easy to integrate with any of our systems."
"I have seen a return on investment with this solution."
"All the features of Apache Kafka are valuable, I cannot single out one feature."
"The stability is very nice. We currently manage 50 million events daily."
"We like the seamless flexibility in protocol exchange offering without writing a code."
"The way we can replicate information and send it to several subscribers is most valuable. It can be used for any kind of business where you've got multiple users who need information. Any company, such as LinkedIn, with a huge number of subscribers and any business, such as publishing, supermarket, airline, or shipping can use it."
"The most useful features has been the WAN optimization and probably the HybridEdge, which requires some third-party adapters or plugins. The idea that we can position Solace as a protocol-agnostic message transport fabric is key to our company having all manners of asynchronous messaging protocols from MQ, Kafka, JMS, etc. I really like the WAN optimization: Send once over a WAN, then distribute locally as many times as there are subscribers."
"One of the main reasons for using PubSub+ is that it is a proper event manager that can handle events in a reactive way."
"In my assessment of Solace against other products — as I was responsible for evaluating various products and bringing the right tool into companies in the past — I worked with multiple platforms like RabbitMQ, Confluent, Kafka, and various other tools in the market. But I found the event mesh capability to be a very interesting as well as fulfilling capability, towards what we want to achieve from a digital-integration-strategy point of view... It's distributed, yet it is intelligently connected. It can also span and I can plug and play any number of brokers into the event mesh, so it's a great deal. That's a differentiator."
"As of now, the most valuable aspects are the topic-based subscription and the fanout exchange that we are using."
"The topic hierarchy is pretty flexible. Once you have the subject defined just about anybody who knows Java can come onboard. The APIs are all there."
"The valuable feature of PubSub+ Event Broker is the speed of processing, publishing, and consumption."
"The solution should be easier to manage. It needs to improve its visualization feature in the next release."
"There are some latency problems with Kafka."
"Kafka has a lot of monitors, but sometimes it's most important to just have a simple monitor."
"More Windows support, I believe, is one area where it can improve."
"The management overhead is more compared to the messaging system. There are challenges here and there. Like for long usage, it requires restarts and nodes from time to time."
"Lacks elasticity and the ability to scale down."
"One complexity that I faced with the tool stems from the fact that since it is not kind of a stand-alone application, it won't integrate with native cloud, like AWS or Azure."
"Apache Kafka has performance issues that cause it to lag."
"The licensing and the cost are the major pitfalls."
"The ease of management could be approved. The GUI is very good, but to configure and manage these devices programmatically in the software version is not easy. For example, if I would like to spin up a new software broker, then I could in theory use the API, but it would require a considerable amount of development effort to do so. There should be a tool, or something that Solace supports, that we could use for this, e.g., a platform like Terraform where we could use infrastructure as code to configure our source appliances."
"Some of the feature's gaps with some of the open-source vendors have been closed in a lot of ways. Being more agile and addressing those earlier could be an area for improvement."
"For improvements, I would suggest increasing the max payload size to a limit of 100MB or more. The current max payload size is limited to 5MB."
"If you create one event in the past, you cannot resend it."
"We have requested to be able to get into the payload to do dynamic topic hierarchy building. A current workaround is using the message's header, where the business data can be put into this header and be used for a dynamic topic lookup. I want to see this in action when there are a couple of hundred cases live. E.g., how does it perform? From an administration perspective, is the ease of use there?"
"The deployment process is complex."
"I would like them to design topic and queue schemas, mapping them to the enterprise data structure."
