Featured Reviews

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.

Reliable change data capture has kept critical databases synchronized in real time
I consider the best features that Striim offers to be great performance and a large number of sources and targets that can be connected. Striim is capable of absorbing a large number of transactions, and the difference between the two databases is always less than a second, which demonstrates efficiency and highlights the variety of sources and targets I have used. Striim has had a positive impact on my organization as it has solved stability issues that I had with other tools.

Quotes from Members

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

Pros

"Apache Flink provides faster and low-cost investment for me; I find it to have low hardware requirements, and it's faster with low code, meaning it's easy to understand for moving the streaming data."
"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 event processing function is the most useful or the most used function. The filter function and the mapping function are also very useful because we have a lot of data to transform. For example, we store a lot of information about a person, and when we want to retrieve this person's details, we need all the details. In the map function, we can actually map all persons based on their age group. That's why the mapping function is very useful. We can really get a lot of events, and then we keep on doing what we need to do."
"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."
"With Flink, it provides out-of-the-box checkpointing and state management. It helps us in that way. When Storm used to restart, sometimes we would lose messages. With Flink, it provides guaranteed message processing, which helped us. It also helped us with maintenance or restarts."
"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."
"The setup was not too difficult."
"Flink moved on to becoming a standard technology for location platform."
"Striim is capable of absorbing a large number of transactions, and the difference between the two databases is always less than a second, which demonstrates efficiency and highlights the variety of sources and targets I have used."
 

Cons

"There is room for improvement in the initial setup process."
"There is a learning curve. It takes time to learn."
"Apache should provide more examples and sample code related to streaming to help me better adapt and utilize the tool."
"Flink has become a lot more stable but the machine learning library is still not very flexible."
"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."
"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's documentation should be available in more languages."
"We have a machine learning team that works with Python, but Apache Flink does not have full support for the language."
"I think Striim could be improved with better pricing and enhanced documentation."
 

Pricing and Cost Advice

"It's an open source."
"It's an open-source solution."
"Apache Flink is open source so we pay no licensing for the use of the software."
