Here are some excerpts of what they said:
Pros
"Apache Spark Streaming is versatile. You can use it for competitive intelligence, gathering data from competitors, or for internal tasks like monitoring workflows.""Apache Spark Streaming's most valuable feature is near real-time analytics. The developers can build APIs easily for a code-steaming pipeline. The solutions have an ecosystem of integration with other stock services.""Apache Spark Streaming has features like checkpointing and Streaming API that are useful.""As an open-source solution, using it is basically free.""The solution is better than average and some of the valuable features include efficiency and stability.""Apache Spark Streaming was straightforward in terms of maintenance. It was actively developed, and migrating from an older to a newer version was quite simple.""The solution is very stable and reliable.""It's the fastest solution on the market with low latency data on data transformations."

"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.""When it comes to granularity, you can literally do anything regarding how the filtering works.""The most valuable feature of PubSub+ Event Broker is the scaling integration. Prior to using the solution, it was done manually with a file, and it can be done instantly live.""When we went to add another installation in our private cloud, it was easy. We received support from Solace and the install was seamless with no issues.""Going from something where we had outages and capacity issues constantly to a system that was able to scale with the massive market data and messaging spikes that happened during the initial stages of the COVID crisis in March, we were able to scale with 40 plus percent growth in our platform over the course of days.""This solution reduces the latency to access changes in real-time and the effort required to onboard a new subscriber. It also reduces the maintenance of each of those interfaces because now the publisher and subscribers are decoupled. Event Broker handles all the communication and engagement. We can just push one update, then we don't have to know who is consuming it and what's happening to that publication downstream. It's all done by the broker, which is a huge benefit of using Event Broker.""The event portal and the diversity of deployment options in a hybrid landscape are the most valuable features.""The valuable feature of PubSub+ Event Broker is the speed of processing, publishing, and consumption."

Cons
"We would like to have the ability to do arbitrary stateful functions in Python.""There could be an improvement in the area of the user configuration section, it should be less developer-focused and more business user-focused.""The service structure of Apache Spark Streaming can improve. There are a lot of issues with memory management and latency. There is no real-time analytics. We recommend it for the use cases where there is a five-second latency, but not for a millisecond, an IOT-based, or the detection anomaly-based. Flink as a service is much better.""It was resource-intensive, even for small-scale applications.""In terms of improvement, the UI could be better.""The solution itself could be easier to use.""The cost and load-related optimizations are areas where the tool lacks and needs improvement.""The initial setup is quite complex."

"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.""The licensing and the cost are the major pitfalls.""I would like them to design topic and queue schemas, mapping them to the enterprise data structure.""The product should allow third-party agents to be installed. Currently, it is quite proprietary.""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?""It could be cheaper. It could also have easier usage. It is a brilliant product, but it is quite complex to use.""A challenge we currently have is Solace's ability to integrate with single sign-on in our Active Directory and other single sign-on tools and platforms that any company would have. It's important for the platforms to work. Typically, they support only LDAP-based connectivity to our SQL Servers.""The deployment process is complex."

Pricing and Cost Advice
  • "People pay for Apache Spark Streaming as a service."
  • "I was using the open-source community version, which was self-hosted."
  • "On a scale from one to ten, where one is expensive, or not cost-effective, and ten is cheap, I rate the price a seven."
  • More Apache Spark Streaming Pricing and Cost Advice →

  • "There are different tiers where you can choose what would work for you. As a customer, you need to know roughly how many messages a month you will use."
  • "We have been really happy with the product licensing rates. It has been free for us, up to a 100,000 transactions per second, and all we have to do is pay for support. Making their product available and accessible to us has not been a problem at all."
  • "Having a free version is critical for our technology operations use case. This is primarily because our technology operations team is a cost center in our company. They are not profit drivers and having a free version for installation will probably meet our needs. Even for production, it'll support up to a 100,000 messages per second. I don't think in technology operations that we have that many events and alerts from our detection tools. Even if I have 20 or 30 event detection products out there, they're only going to publish the things which are critical or warnings. I don't think we'll ever reach a 100,000 messages per second."
  • "Having a free version of the solution was a big, important part of our decision to go with it. This was the big driver for us to evaluate Solace. We started using it as the free version. When we felt comfortable with the free version, that is when we bought the enterprise version."
  • "The pricing and licensing were very transparent and well-communicated by our account manager."
  • "We are looking for something that will add value and fit for purpose. Freeware is good if you want to try something quickly without putting in much money. However, as far as our decision is concerned, I don't think it helps. At the end of the day, if we are convinced that a capability is required, we will ask for the funding. Then, when the funding is available, we will go for an enterprise solution only."
  • "The licensing is dependent on the volume that is flowing. If you go for their support services, it will cost some more money, but I think it is worth it, especially if you are just starting your journey."
  • "It could be cheaper. Its licensing is on a yearly basis."

    Reviews from Real Users

    PubSub+ Event Broker stands out among its competitors for a number of reasons. Two major ones are its ability to communicate with numerous subscribers and its scalability. PeerSpot users take note of the advantages of these features in their reviews:

    Jitendra J., a websphere MQ specialist at a maritime company, notes, “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 head of enterprise architecture and digital innovation at a tech vendor writes, “This solution reduces the latency to access changes in real-time and the effort required to onboard a new subscriber. It also reduces the maintenance of each of those interfaces because now the publisher and subscribers are decoupled. Event Broker handles all the communication and engagement.”

    Another PeerSpot user, who is a senior project manager at a financial services firm, describes, "Going from something where we had outages and capacity issues constantly to a system that was able to scale with the massive market data and messaging spikes that happened during the initial stages of the COVID crisis in March, we were able to scale with 40 plus percent growth in our platform over the course of days."
