We performed a comparison between Denodo and Talend Open Studio based on real PeerSpot user reviews.
Find out in this report how the two Data Integration solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."It allows a lot of traceability and you can decide what data you want to collect"
"The most valuable features are query optimization and the single language independence from the sources we're using to catch data."
"Access to numerous forums and internet information."
"Data mining is one of the valuable features. We're able to connect all of the data sources with the installed driver, so that is a good advantage in Denodo. Being able to join the tables and view them is also valuable."
"The data abstraction is the most valuable feature."
"The most valuable feature is Data Catalogs."
"Denodo is very stable."
"In PL/SQL, first you need to gather all the data and then start writing the file, but in Denodo you fetch the data and write the data simultaneously. So, for example, if you have 1 million or 2 million records, you don't have to wait to fetch all of the 2 million; you can keep on fetching and writing in the file simultaneously."
"A helpful feature for us is the integration with NoSQL databases."
"The solution has a good balance between automated items and the ability for a developer to integrate and extend what he needs. Other competing tools do not offer the same grade of flexibility when you need to go beyond what is provided by the tool. Talend, on the other hand, allows you to expand very easily."
"We have contacted their technical support. They are great. They offer very professional help. If I need some technical answer, they are very professional. They are quick, professional, and very accurate."
"There are many architectures: hybrid, cloud, and on-prem."
"The initial setup of the product was very easy."
"This product is very easy to use."
"The drag-and-drop feature in the interface is very good."
"The most interesting aspect of the solution for us is that Talend Open Studio has a good balance between the features and the cost of the data management platform."
"Tasks such as conversion of a date format or conversion of a number format that can be done in a very easy way in different languages, like SQL or Oracle, are not so easy to do in Denodo. For example, if you want to convert a date from one format to another, in Oracle it's pretty easy; in Denodo, however, it requires so many lines of code. Simple things that can be done very quickly in other database languages require more lines of code in Denodo."
"The dropdown menus feel antiquated to me, and the administrative portals need improvement."
"We would like this solution to be more universally user-friendly. At present it is really only aimed at IT specialists."
"The solution is slow when there are many virtualization layers."
"Lacks integrations with AWS, GCP and the like."
"Sometimes, Windows-related functions do not work properly in Denodo. The analytic functions in SQL do not work properly."
"Denodo can improve usage management-related aspects. If you deal with the mini views, it gets stuck. The performance is very slow when we go with a large number of views and high volume."
"I would like to see a proper way to avoid killing the sourcing systems."
"The pricing could be lower. They should work to make it more affordable."
"It is complicated to understand the configuration process for email components."
"Talend Open Studio's interface does not provide a good experience...I would like to see better documentation and a more enhanced graphical interface in Talend Open Studio."
"The documentation is lacking within the product. They need to get better at all aspects of describing how it works and how to use it."
"In terms of features, it has all the features that I need. However, it consumes a lot of resources. It is using a lot of RAM, and they need to fix the issue related to resource consumption. It currently requires more than 24 gigabytes of RAM, which is a big amount of RAM."
"Having additional training materials, such as a video tutorial, would be an improvement."
"The solution needs more integrations."
"In the next release, Open Studio should include cloud storage as an input."
