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.

Real-time replication has transformed data loads but needs clearer logs and better documentation
Striim offers strong capabilities for real-time database replication. Its core strength is low latency, log-based change data capture, which continuously moves the data without putting heavy load on the source systems. It works especially well in Oracle environments and supports more than 150 sources and targets, including Snowflake, Databricks, and Microsoft Fabric, which is hot in the market right now. It handles the initial load and the ongoing CDC in one platform so we do not have to stitch together Kafka or similar processes ourselves. It offers high availability clustering with failovers and can run self-hosted or fully managed on cloud services. The user interface is pretty good and self-explanatory, so there is no issue if a user lands in the application; they do not have to think more. It is self-explanatory, with all the navigation panes clear. However, the only thing is the searchability; if a user has to search which table belongs to which CDC application connection set up on Striim, it is quite extensive and not fruitful from a user interface point of view. Performance-wise, it is quite good; the queues are long, but as I mentioned earlier, the logs are not that self-explanatory that one can understand what exactly is going on behind the scenes.

Quotes from Members

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

Pros

"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."
"Allows us to process batch data, stream to real-time and build pipelines."
"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."
"Apache Flink offers a range of powerful configurations and experiences for development teams. Its strength lies in its development experience and capabilities."
"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."
"It is user-friendly and the reporting is good."
"The setup was not too difficult."
"Apache Flink's best feature is its data streaming tool."
"Striim's technical support is the best and at par with competitors."
"We were confidently in a situation to call Snowflake as a single source of truth, and I believe with Striim, we were able to do that because without Striim, the SLA would be much higher, and there would not have been much confidence in Snowflake."
"Striim's intuitive UI for monitoring, the flow designer, and the real-time console are straightforward and helpful."
"Striim is definitely my data migration tool and data reflection syncing tool. It reduces manual intervention because it automatically syncs the data from the warehouse."
"Striim offers strong capabilities for real-time database replication with low latency, log-based change data capture, which continuously moves the data without putting heavy load on the source systems."
"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."
"The CDC works nicely by replicating data as changes happen to the source database, running syncs to the target, and applying changes in near-real time."
 

Cons

"One way to improve Flink would be to enhance integration between different ecosystems."
"There are more libraries that are missing and also maybe more capabilities for machine learning."
"We have a machine learning team that works with Python, but Apache Flink does not have full support for the language."
"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."
"Amazon's CloudFormation templates don't allow for direct deployment in the private subnet."
"Apache Flink's documentation should be available in more languages."
"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. 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."
"I think Striim could be improved with better pricing and enhanced documentation."
"The user experience of triggering alerts if there's any lag which Striim identified, which is not normal, could intrinsically be done by Striim."
"I would say Striim performance needs improvement because we use more GoldenGate, so I tend to compare GoldenGate with Striim."
"Pricing is too high compared to other replication tools currently available in the market, especially Fivetran."
"Customer support was non-existent, with some documentation shared by Google personnel but no access to a customer portal for support tickets."
"Striim can be improved by providing tools such as short videos or step-by-step manuals to clearly demonstrate its capabilities and help users learn quickly."
"The pricing is a bit on the higher end for Striim."
 

Pricing and Cost Advice

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