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.

A solution with useful windowing features and great for operations and marketing
The persistence could be better. Although ESP is designed for in-memory processing, it would be better if the solution is enhanced or improved on the persistence of the data that is kept in the memory. For example, if one server goes down and the information is stored in the memory, it is lost. Therefore, the persistence needs to be improved so that if there are more cases where the server is down, the information and data can still be intact.

Quotes from Members

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

Pros

"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."
"Easy to deploy and manage."
"Flink moved on to becoming a standard technology for location platform."
"Apache Flink offers a range of powerful configurations and experiences for development teams. Its strength lies in its development experience and capabilities."
"The end-to-end latency was drastically reduced, and our capability of handling high throughput has increased by using Flink."
"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."
"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 solution is beneficial on an enterprise level."
 

Cons

"The solution could be more user-friendly."
"One way to improve Flink would be to enhance integration between different ecosystems."
"Apache Flink's documentation should be available in more languages."
"One way to improve Flink would be to enhance integration between different ecosystems. For example, there could be more integration with other big data vendors and platforms similar in scope to how Apache Flink works with Cloudera. Apache Flink is a part of the same ecosystem as Cloudera, and for batch processing it's actually very useful but for real-time processing there could be more development with regards to the big data capabilities amongst the various ecosystems out there."
"Amazon's CloudFormation templates don't allow for direct deployment in the private subnet."
"We have a machine learning team that works with Python, but Apache Flink does not have full support for the language."
"There is a learning curve. It takes time to learn."
"PyFlink is not as fully featured as Python itself, so there are some limitations to what you can do with it."
"The persistence could be better."
 

Pricing and Cost Advice

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