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

"This solution provides us with the ability to sync data, and make it available for anyone to use across the business."
"The most valuable feature in Denodo is data virtualization."
"It allows a lot of traceability and you can decide what data you want to collect"
"Denodo is lightweight in terms of how it leads you to combine your discrete data systems at one spot."
"The best thing about Denodo is that creating and deploying a web service can be done in about 10 minutes, compared to a whole day when it comes to other solutions (such as when deploying with Java and AWS)."
"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."
"The most valuable aspects of this solution are the short time frame in which you can deliver and connect."
"The most valuable feature is Data Catalogs."
"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."
"The data integration aspect of the solution is excellent."
"The most valuable features are definitely data integration, data preparation, and data stewardship."
"The API integration and big data approach are very good because of how you extract data from JSP files or big data web repositories like MongoDB."
"The most valuable feature of Talend Open Studio is the tMap component. There is a lot of functionality in one component."
"I can connect with different databases such as Oracle Database or SQL Server. It allows you to extract the data from one database to another. I can structure the data by filtering and mapping the fields. It is very user-friendly. You need to know the basics of SQL development or SQL queries, and you can use this tool."
"The most valuable feature for me when it comes to this solution is that it's easy to use."
"Talend Open Studio's installation process is easy. One just needs to install Java before installing the product"
 

Cons

"Documentation needs to be improved"
"The integration could use improvement, it's a lot of non-speed line processes that we have discovered, in the country. The configurations could use a lot more improvement."
"Denodo has some difficulty supporting large numbers of records."
"Monitoring event logs can be improved. In the older version, there was a monitoring schedule to get event reports and properly audit the reports. In the newer version, it is not there, and we have to manually configure data and audit events."
"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."
"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."
"The solution is slow when there are many virtualization layers."
"The cache configuration is more complicated."
"The profiling perspective needs improvement. Instead of using it in the studio, we are using a different tool which is also provided by Talend. It's redundant."
"Having additional training materials, such as a video tutorial, would be an improvement."
"The technical support and documentation need a lot of work to come up to standard."
"Inter-version compatibility is a problem, and migration projects between versions are required."
"In version 6.2 we did encounter issues with the job servers and specifically with ESB. Version 6.3 is better but large jobs can cause the MDM server to fall over, requiring a reboot."
"It is not as visually appealing as some of the other tools."
"In the next release, Open Studio should include cloud storage as an input."
"The physical appearance of the product is an area of concern where improvements are required."
 

Pricing and Cost Advice

"Talking with my manager and others, nobody has complained about the pricing so far which is a positive sign."
"There is an express edition and a licensed enterprise edition."
"For us, the cost has been okay. Also, there are no additional costs; it's just the standard licensing fee."
"The pricing is pretty good, and I would rate it at four out of five."
"Denodo provides a lightweight 30-day free trial, but when we do courses on top of it, it costs $150 for each person."
"I don't know the actual cost, but it's tens of thousands of dollars per month."
"Depending on the size of the client you want to work with, it can be prohibitively expensive at times."
"I am not super familiar with the pricing, but so far, it seems good. We have been happy. We haven't seen any problems. The only time we had to pay extra was during the upgrade. We didn't upgrade at the time they told us to upgrade, and we had to pay extra to keep the service. They had stopped the support for the older version and moved to the newer version. It was not their fault. It was our fault because we didn't get on board quickly."
"It does the job well for nothing — without cost. That's the advantage of this product."
"I am using the open-source version of the solution, so there are no extra costs for any feature."
"The cost, particularly in Africa, is quite high."
"It is an open-source tool which means it is a free solution."
"Price could be lower. It is getting too expensive when compared to some other solutions, which is actually a little bit concerning."
"It is an open-source product."
"Talend Open Studio is priced too high."
"We are using the free version of the tool, because the enterprise version is a little expensive."
