Atanu Chatterjee - PeerSpot reviewer
Data virtualization and integration enabled while caching and scalability room for improvement
In terms of improvements for Denodo, regarding performance, in cases where there are multiple virtualizations—such as reading from one Denodo view that is virtualized, and from that view there's also virtualization, and another team is reading from that view—if multiple virtualizations happen with no caching in between, it becomes slow. This occurs because it is cascading; whenever at the top level someone is reading data, that request is getting cascaded to the nth level, causing issues, especially in cases such as Power BI reports. We need to consider implementing some persistent layer in between. The scaling process should improve because many things are getting automated. The scale-out part needs to be automated, though I am uncertain whether Denodo has already implemented that feature.
Costin Marzea - PeerSpot reviewer
Allows you to develop your own components and can be used as an OEM
Sometimes, scalability is part of planning. It depends on what you mean by scalability. People talk a lot about it, but scalability is not always about system functionality. Sometimes, it may be planning the job you're doing. If you want to split it into several jobs or servers, you don't actually have to have it built in as a functionality. You can create a job using a loop, which runs and controls several jobs in a loop that may be controlled. Scaling should not always be part of the infrastructure based on whether the engine can scale or not. I think it's your plan or project that should scale and split, and you can define these parameters. These parameters include how many servers you want to run or how many executions you want to do on different parts of the data. It's not always an issue of the engine running. Sometimes, your database should be configured to support partitioning. The product may scale very well without partitioning, but if the basic response is very slow, you didn't solve the problem. You should solve the problems at a higher level, not just at the execution level. They should be solved at the database level and communication level, and you should have firewalls. We are trying to add to the open source the ability to generate code for containers and Kubernetes that exist in the subscription version. Once you do this, Kubernetes will take care of the scaling, so there is no problem.

Quotes from Members

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

Pros

"The GUI interface allows easy connection of all data sources like API, JSON, or any JDBC source."
"The data abstraction is the most valuable feature."
"We can consume data fast."
"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."
"In general, it's good for us to make tests so we can scout the data."
"This solution provides us with the ability to sync data, and make it available for anyone to use across the business."
"Denodo is lightweight in terms of how it leads you to combine your discrete data systems at one spot."
"The data catalog feature is valuable as it helps define data structures without storing data."
"Talend Studio has the ability to use it to ensure data quality."
"You can use Talend SDK to develop your own components and add them to the product."
"This is a user-friendly solution that is easy to use."
"We're able to handle large amounts of data with ease."
"The solution's technical support is responsive and helpful."
"This product is very easy to use."
"It is easy to use and covers most of the functions needed. We can use the code without any extra effort. The open source is very good. They have the same commercials with additional connectors. The graphical design environment is also very easy."
"It's a good tool. It has the ability to take apart and install whatever we need. It's very good for data, transformation, and loading."
 

Cons

"We would like this solution to be more universally user-friendly. At present it is really only aimed at IT specialists."
"We can't scale it to meet digital requirements."
"Denodo currently integrates with ChatGPT, but the ability to manage and utilize them directly within Denodo would be a significant improvement."
"The support is not the best and should be improved."
"It requires improving the story of how it can solve specific problems."
"User-specific security at the column and row levels needs to be improved. Instead of applying security at every individual level, it would be better if it were at the group or tier level. It will save a lot of time."
"I am still waiting for Denodo to support vector databases."
"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."
"Having additional training materials, such as a video tutorial, would be an improvement."
"The stability of the solution could improve when running jobs. There can be errors when running projects but in the end, it works well and the errors do not impact the result."
"There used to be many Youtube channels that offered Talend training, but now there don't seem to be any. The solution should offer more online training resources."
"It is complicated to understand the configuration process for email components."
"Multiple products are there within the product suite. That can be actually trimmed down."
"It doesn't have the ability to keep the repository of the source code (visual pipeline). It can be integrated with Git."
"When faced with a challenge, such as the necessity to link up with an unconventional data source like the legacy Cyprus Vision database that wasn't inherently supported by Talend, I had to resort to writing Python code to establish the connection."
"The only other thing is that you have to integrate into an API gateway. We're in Azure, so we use Microsoft Azure Gateway. It doesn't come with its own gateway, which is another sort of big plus side that we saw in Boomi. Talend isn't quite there yet with the API gateway."
 

Pricing and Cost Advice

"Depending on the size of the client you want to work with, it can be prohibitively expensive at times."
"For us, the cost has been okay. Also, there are no additional costs; it's just the standard licensing fee."
"The licensing should be improved, as the cost per connector is quite expensive."
"There is an express edition and a licensed enterprise edition."
"I don't know the actual cost, but it's tens of thousands of dollars per month."
"Cost wise, on a scale from one to five, with one being the cheapest and five being the most expensive, Denodo would be at three. We get all the features in a bundle."
"The cost for Denodo is in line with other similar products."
"The pricing is pretty good, and I would rate it at four out of five."
"I am using the open-source version of the solution, so there are no extra costs for any feature."
"Talend is free and you can download it."
"We are using the free version of the tool, because the enterprise version is a little expensive."
"Price could be lower. It is getting too expensive when compared to some other solutions, which is actually a little bit concerning."
"There are many versions available and one is open-sourced which is free."
"Pricing is always a challenge. It is quite an expensive model, but because the platform is so simple to use, we haven't had to purchase any additional licenses."
"For Talend Open Studio, there is a need to make yearly payments towards the licensing cost. Talend Open Studio is a bit expensive, in my opinion."
"Open Studio has a basic license and additional costs for services, including customer support and technical assistance."
