It has helped us improve our latency performance drastically

As a large scale high performance trading platform serving the high frequency trading community, latency has always been critical for our clients. Before using Azul Zing JVM, we would have had to spend a lot of effort tuning our JVM GC and profiling our application to minimize latency, which is…

Consulting team maximizes cloud features while seeking workflow improvements

We are quite satisfied with the solution. The only issue we face is with the workflow feature. Every time we need to deploy our workflows, we must contact the Reltio Support Center. We have to rely on their availability and write to them to receive the required JAR files. They are slow to respond to these requests.

Quotes from Members

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

Pros

"The non-stop garbage collector (C4 - Continuously Concurrent Compacting Collector) is the most valuable feature."

"GC Pause times are maintained in low milliseconds, which is beneficial for applications with high volume, high memory allocation rate, and a high memory footprint, and it also increases throughput by approximately 20-25% as compared to Oracle Java Development Kit based on some tests that I have done with real applications."

"Performance of the JVM, especially the C4 Pauseless Garbage Collection, for continuous application execution is the most valuable feature."

"Zing has completely solved the garbage collection problem for us."

"With Zing, we've now been able to re-allocate those tuning resources to general product development."

"With minimal effort, Zing has helped us improve our latency performance drastically."

"No other JVM on the market even comes close to competing with the Azul Zing."

"With minimal effort, Zing has helped us improve our latency performance dramatically."

More Azul Zing pros

"It is a scalable product, and the scalability is good. We can configure users."

"Reltio Cloud has positively impacted my organization by reducing the amount of manual effort needed and making it easy to manage downstream systems."

"The cloud feature is very beneficial, and the scalability performance feature is excellent."

"The survivorship feature is great because we can define it, prioritize the sources, and only allow those sources to survive when making the golden record."

"The matching feature of Reltio Cloud is highly effective compared to many other tools available. Additionally, it is almost ready to use out-of-the-box, reducing the implementation time."

"There are default limitations and considerations. For instance, Reltio can store a maximum of 200 values for a single attribute. If your data exceeds this limit, you can request Reltio support to increase the limit. However, be aware that increasing this limit may impact performance, potentially slowing down data loading times."

"The most valuable feature is real-time synchronization. You can see the events as soon as they are posted within a couple of fraction seconds."

"The most valuable feature of Reltio Cloud is the customization we can make in its functionality."

Cons

"It is extremely expensive."

"However, like every other great product, there is always something that can be improved."

"Although Azul claims to have a fast warmup, we still experience higher latency for the first trade when our system starts up on Sundays."

"We have encounter stability issues and that has been a source of frustration at times."

"Although Azul claims to have a fast warmup, we still experience higher latency for the first trade when our system starts up on Sundays."

"The licensing over non-production environments considerably affects the cost of our solution as a software vendor."

"The profiling tools included with Zing lag behind those available for Oracle's Java implementation."

"The solution's UI could be enhanced, and its record filtering could be expanded."

"Sometimes, the service goes down for maintenance or when we run a lot of jobs so things get pushed to the queue and results don't get delivered on time."

"The support team is slow to respond when we need assistance with workflow deployments. We must rely on their availability and contact them to receive the required JAR files."

"We need manual data modeling and configuration to tailor the platform to our requirements."

"The download process can be quite slow"

"Initially, the UI was limited in features."

"Reltio Cloud can be improved by providing the possibility to connect with other connectors and databases such as Snowflake, Databricks, and eventually with Azure Data Factory."

"The deployment is difficult."
