While the solution scales well on a single machine, I have doubts about its scalability when deployed as part of a Java component cluster.

Its complexity in configuring and the requirement to install different connectors for different sources affects its scalability.

Setup Cost

Denodo's CPU/cores-based pricing is costly for small businesses but fair for larger enterprises, including some extra fees.
Talend Open Studio is free; paid versions offer more features but may be costly with robust infrastructure requirements.
For small companies, it's not a solution that most small companies can afford.
Senior Backend Engineer at a pharma/biotech company with 51-200 employees
Denodo is considered pricey, limiting its use to large enterprises or government organizations that can afford its comprehensive setup.

Valuable Features

Denodo enhances data integration through virtualization, offering performance, usability, and seamless access to diverse data sources without replication.
Talend Open Studio is acclaimed for its user-friendly interface, extensive connectors, and flexible data integration capabilities, enhancing usability.
Denodo's ability to connect to multiple data sources and perform extract-transform-load (ETL) operations on the fly is noteworthy.
Director Software Engineer at a computer software company with 10,001+ employees
The most valuable feature of Denodo is its uniformity of self-site data access types, which allows it to connect to almost any storage technology and feed it transparently.
Datawarehouse & BI consultant, Owner, Mananging partner at NesCon B.V.
Denodo supports SQL base, so if you want to join two tables or two views, you can use SQL, which is an advantage as most developers or business people know SQL.
Principal Architect at a manufacturing company with 10,001+ employees
It also comes with a console which helps us to monitor the jobs we have built in, making that monitoring part easy.

Featured Reviews

Douglas Camargo - PeerSpot reviewer
Senior Backend Engineer at a pharma/biotech company with 51-200 employees
Has simplified multi-database querying and accelerated solution delivery with minimal setup
Denodo offers a great query language, the VQL, which was very easy to understand for someone that only knows SQL. It was easy to work with, and it was easy to integrate various types of databases in general. The usability of the platform is very great. The federated queries were also a feature that I used a lot. The easy usability of Denodo helped my work and made things easier for productivity. We were able to ship code faster than if we needed to use another type of data visualization tool or even an ETL. When we have multiple databases, the standard or common approach is just to have an ETL that matches the data, and we need to write this whole ETL. With Denodo, we can simplify this whole work to a few queries or setups in the databases and just make a few queries. This was actually easier, and it was faster to deliver a solution for a client instead of building a whole ETL pipeline or simply backfilling one database in another. Denodo simplifies your work and helps you ship code or ship solutions in a faster way. I really like the UI that Denodo has on the web app version. It was very simple and actually very beautiful to see. For a complicated program, it was very easy to understand how it works, even for someone who is just approaching the data engineering career or side of the programming language.

Has supported building flexible data pipelines and streamlined ETL orchestration
There should be a dedicated support team for Talend Open Studio. We do have a support team, but at times it is critical for us to fix certain things within one or two hours. Usually, the support team takes some 12 hours, which is the standard edition of support. If we could have round-the-clock support, we would be able to resolve many issues which we encounter during the development part. The initial setup for Talend Open Studio is a little complex. We need to have a dedicated person who has an understanding of Talend Open Studio as a tool. It takes some level of expertise, so it is not an easy process, but once we have a dedicated associate who is knowledgeable in that particular field, it becomes comparatively easier.
