Sanjay Srivastava - PeerSpot reviewer
Software Architect at IBM
Streaming workflows have improved data integration and support real-time pipelines across platforms
We are not using Apache Flink in its advanced window capabilities. We are using the Apache Flink job in Apache SeaTunnel, meaning we can write the code inside Apache SeaTunnel. Currently, we are moving; both solutions are there. We are doing it on-premises with the help of Kubernetes and OpenShift. The main reason why Apache Flink is better is that it has more functions, and being open source with easy code in Apache SeaTunnel helps us achieve that. Cost is a major issue. I would rate the stability of the product as an eight. For Apache Flink, the final point can be rated an eight. I can recommend Apache Flink to other users for streaming support, and I am recommending it. I would rate this review an eight overall.

Centralized visibility has streamlined daily monitoring and troubleshooting of message flows
The best features of Kpow for Apache Kafka are real-time monitoring and powerful troubleshooting capabilities. I especially appreciate how easy it is to inspect topics, browse messages, monitor consumer groups, and track consumer lag from a single dashboard. The search and message inspection features make it much faster to debug production issues without relying heavily on command-line tools. Kpow for Apache Kafka has had a positive impact on our organization. It has reduced the time required to monitor Kafka clusters and troubleshoot issues, allowing the team to identify and resolve problems much faster. Having a centralized dashboard with clear visibility into topics, consumer groups, and message flow has improved our operational efficiency and reduced our reliance on command-line tools. Overall, it has helped streamline our Kafka management and made it easier for both developers and operations teams to collaborate when investigating issues.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Among all of this, if I would talk about streaming, Apache Flink wins hands down, but there are other products like Apache Pulsar which I have no idea."
"We are very happy with the product, and we have been able to achieve all of the use cases that we are expected to deliver for our customers."
"The documentation is very good."
"Another feature is how Flink handles its radiuses. It has something called the checkpointing concept. You're dealing with billions and billions of requests, so your system is going to fail in large storage systems. Flink handles this by using the concept of checkpointing and savepointing, where they write the aggregated state into some separate storage. So in case of failure, you can basically recall from that state and come back."
"The top feature of Apache Flink is its low latency for fast, real-time data. Another great feature is the real-time indicators and alerts which make a big difference when it comes to data processing and analysis."
"The setup was not too difficult."
"Allows us to process batch data, stream to real-time and build pipelines."
"It provides us the flexibility to deploy it on any cluster without being constrained by cloud-based limitations."
"Kpow for Apache Kafka has positively impacted my organization and has been very beneficial."
"Using Kafka instead of something such as IBM MQ is much cheaper, offering scalability and processing messages in parallel, which Kafka helps manage quite a lot, though you can have issues with duplicate processing."
"Overall, Kpow for Apache Kafka has scaled well with our environment and has remained responsive and reliable as our workload increased."
"The best feature of Kpow for Apache Kafka is that it can actually scale up."
"Kpow for Apache Kafka makes development faster because integration with Kafka can be quite complex and requires significant research and development effort, however, with Kpow for Apache Kafka, you can use a simple integration process to handle all of these aspects."
 

Cons

"In a future release, they could improve on making the error descriptions more clear."
"The solution could be more user-friendly."
"The technical support from Apache is not good; support needs to be improved. I would rate them from one to ten as not good."
"Apache Flink should improve its data capability and data migration."
"Apache Flink is very powerful, but it can be challenging for beginners because it requires prior experience with similar tools and technologies, such as Kafka and batch processing."
"There are more libraries that are missing and also maybe more capabilities for machine learning."
"I am using the Python API and I have found the solution to be underdeveloped compared to others. There needs to be better integration with notebooks to allow for more practical development."
"One way to improve Flink would be to enhance integration between different ecosystems."
"I am saying that the cloud version is quite expensive, and there's room for improvement since I've set up a test cluster on my own AWS account, and within the first couple of days, it already accumulated a bill close to $200-$300 with no activity on the cluster."
"To improve Kpow for Apache Kafka, I believe that even though the UI is really user-friendly, it can be made more intuitive."
"Kpow for Apache Kafka can sometimes be overkill if my data set is small because I will end up paying for the cluster and retaining it and managing the clusters."
"However, the default resource allocation is very limited."
"Kpow for Apache Kafka is a strong product, but there are a few areas where it could be improved."
 

Pricing and Cost Advice

"This is an open-source platform that can be used free of charge."
"Apache Flink is open source so we pay no licensing for the use of the software."
"It's an open source."
"The solution is open-source, which is free."
"It's an open-source solution."
