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.

Unified monitoring has improved real-time visibility and simplified secure data diagnostics
I believe Kpow for Apache Kafka is already in a pretty good state. However, the default resource allocation is very limited. I would suggest they increase the best resource requirements. The default requires around 2 GB to 8 GB, which is relatively high for a UI tool that could be scaled through one CPU to 2 GB for a single cluster. I chose the number eight because it has a very good GUI for handling Apache Kafka. However, there are some improvements that should be made. Since it is not a free tool and you have to pay for it, there is no testing possible without paying something. This is not ideal for those who want to try the free version. There are no other improvements needed for Kpow for Apache Kafka that I haven't mentioned.

Quotes from Members

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

Pros

"Apache Flink offers a range of powerful configurations and experiences for development teams. Its strength lies in its development experience and capabilities."
"What I appreciate best about Apache Flink is that it's open source and geared towards a distributed stream processing framework."
"The main advantage is the turnaround time, which has been reduced drastically because of Apache Flink, and now everything is in almost real time with no waiting or lag of data in the application while machine resources are utilized much more efficiently."
"Apache Flink is meant for low latency applications. You take one event opposite if you want to maintain a certain state. When another event comes and you want to associate those events together, in-memory state management was a key feature for us."
"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."
"It is user-friendly and the reporting is good."
"The product helps us to create both simple and complex data processing tasks. Over time, it has facilitated integration and navigation across multiple data sources tailored to each client's needs. We use Apache Flink to control our clients' installations."
"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."
"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."
"Kpow for Apache Kafka has positively impacted my organization and has been very beneficial."
 

Cons

"Apache Flink should improve its data capability and data migration."
"In terms of stability with Flink, it is something that you have to deal with every time. Stability is the number one problem that we have seen with Flink, and it really depends on the kind of problem that you're trying to solve."
"There are more libraries that are missing and also maybe more capabilities for machine learning."
"The state maintains checkpoints and they use RocksDB or S3. They are good but sometimes the performance is affected when you use RocksDB for checkpointing."
"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."
"We have a machine learning team that works with Python, but Apache Flink does not have full support for the language."
"Apache Flink's documentation should be available in more languages."
"Apache should provide more examples and sample code related to streaming to help me better adapt and utilize the tool."
"However, the default resource allocation is very limited."
"To improve Kpow for Apache Kafka, I believe that even though the UI is really user-friendly, it can be made more intuitive."
"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."
 

Pricing and Cost Advice

"The solution is open-source, which is free."
"It's an open source."
"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 solution."
