Ahmed_Emad - PeerSpot reviewer
Territory Sales Leader at Sumerge
A solution for data pipelines but has connector limitations
We have used Kafka for seven years. IBM streams gives you many OOTB features that can boost the time-to-market, especially when it comes to reporting and monitoring for example. Confluent is recognized as one of the leaders in this space and the main reason for this is related to the complete vision of the platform also the large number of connectors. This gives the edge and competitive advatnage.
ArpitShah - PeerSpot reviewer
Software Analyst at CLSA
Event streaming has simplified video data cleanup and now powers real-time analytics
One area for improvement is providing more examples. For instance, Redpanda could be more useful as a sink where you get the data and can directly push to S3. While this is possible through the API, there are better and faster ways to do it. You can make a million API calls and accomplish the task in one and a half hours, but the same thing can be done in ten minutes through other methods. These faster approaches are not documented in obvious places. You have to find information scattered across various blogs. Redpanda should collect all the good blogs and best practices and put them in their documentation. This is more about knowledge management and making it easy for users to understand the product for complex use cases. For simple use cases, it is straightforward. We all use the basic pipe functionality. However, providing more examples would be useful. For example, integration with AWS and the AWS ecosystem would be cool.

Quotes from Members

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

Pros

"The OEM Solution (Excel-medical.com) running on top of IBM Streams provides real-time clinical algorithms that can give better insight into the patient's acuity, thus cutting off time to discharge patients and inversely making sure that sick patients don't get discharged until ready."
"As a result, the TELCO company was able to cut down the time it took to respond to customer needs and there were fewer complaints."
"Easy development and deployment, Java implementation features, and the real time analyser and alarm function are the most valuable features for us."
"The product has enabled us to create solutions to client problems that would have either been impossible or very expensive/difficult using other technologies."
"I think Redpanda will dominate the market in the future, and it will be a really strong contender regarding streaming and AI."
"I do want to mention that there was a part of Redpanda where you can configure and create containers with Docker."
"I have seen positive outcomes including improved efficiency, cost savings, and better performance metrics because it is open-source, fast, and good."
"The performance is superb, and the value we are getting for the money we pay is great."
"I would recommend Redpanda to others because it's easy to set up, consumes less resources, and is stable compared to other tools."
"Redpanda was simple and fast, so we went with Redpanda and it just works."
"The good part about Redpanda is that there is a free part, which is great, and it is embedding most Kafka features so you have a number of features similar to Confluent but for free, which is great."
"Redpanda has positively impacted my organization because the process is now easy and we have not used another streaming platform for comparison, but it has been better than Kafka."
 

Cons

"I’d like to see a tool kit specifically targeted at incremental machine learning. It’s already great for scoring previously trained models, but dynamically updating models is currently more of a 'grow your own' kind of thing."
"The development IDE sometimes crashes and freezes."
"We had some stability issues where we used embedded Zookeeper in production."
"The price and versatility of this product need to improve - it is not inexpensive."
"For me, I was trying to get a lot of data, but I would only get one day's worth of data, even though I asked how I could increase the retention size."
"One area for improvement is providing more examples."
"I think Redpanda needs to increase the connector options."
"In Redpanda, the areas that have room for improvement are in the clustering part."
"We had one incident that we concluded was a case of memory leak."
"When it comes to self-hosting, their documentation could be improved."
"Redpanda can be improved in several ways, and the more I experiment with the product, the more limitations I find."
"One issue I had with Redpanda was debugging an issue where our API would stall whenever we output to our API, and I was not seeing anything in the logs explaining why it was taking a long time."
