Vishal_Goyal - PeerSpot reviewer
The data catalog feature helps define data structures without storing data
The data catalog feature is valuable as it helps define data structures without storing data. Denodo's ability to connect to multiple data sources and perform extract-transform-load (ETL) operations on the fly is noteworthy. It supports API usage to call and present data in JSON or Tableau format without visualization capabilities.
Jason Hale - PeerSpot reviewer
Intuitive interface and documentation make it simple to build jobs and APIs and logging helps pinpoint and resolve issues quickly
Talend is doing a lot of work at the moment, and it's not there yet, but the whole platform could be managed in a SaaS-type environment. You still need to have the Studio running on a virtual desktop or a PC. They will get to be able to do the whole thing inside your browser, so you don't need to install anything locally. It's down the track, and it's the nirvana that we were looking for in Boomi. But the biggest challenge they have is that the platform is so focused on the Studio for all of its development. They'll probably get there, but they have such a mature Studio client that it's a huge amount of work to get all of that functionality into a browser or SaaS platform. That's pretty much the biggest flaw with the Talend environment—being reliant on the Studio, which needed to be on a local machine. 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. Other than that, it's bloody hard to find something because it just seems to be all good.

Quotes from Members

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

Pros

"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."
"While we may not be using all the features of Denodo at this time, we have found the data virtualization features to be very useful in helping us connect our data sources together, bringing all our data into one platform."
"The most valuable feature in Denodo is data virtualization."
"The most valuable features are query optimization and the single language independence from the sources we're using to catch data."
"This solution provides us with the ability to sync data, and make it available for anyone to use across the business."
"It provides useful APIs and integrates with other systems."
"The ability to transfer data is very valuable."
"The most valuable features of Denodo are the extraction option for adapters, and there are many things for the views, that are cached. Denodo is not storing the data, it looks first to tune the query, and these things are for the agents."
"Talend is safe to use because it is very restrictive. It is easy to use when one learns how to manipulate data with SQL."
"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 of Talend Open Studio is the tMap component. There is a lot of functionality in one component."
"The rapidity of integration with data may be one of the valuable features."
"Open Studio's best features are that it's user-friendly, even for beginners, and very easy to implement."
"Talend Open Studio's installation process is easy. One just needs to install Java before installing the product"
"The Talend Studio connected to the Talend MDM (Master Data Management) is the most valuable feature. Talend Studio is used to create a job stream that connects to multiple data sources, matches, compares or creates a golden record for overall identification. It also has a good catalogue of objects that can be dragged and dropped for building models."
"Talend Studio has the ability to use it to ensure data quality."
 

Cons

"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."
"Lacks integrations with AWS, GCP and the like."
"We occasionally have some integration issues that we need to work through."
"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 connectivity option with third-party apps, for example, JDBC, and ODBC drivers. Currently, we need to install it separately from the Denodo side and then connect it."
"The solution should have its own acceleration technology."
"The solution is slow when there are many virtualization layers."
"The cache configuration is more complicated."
"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."
"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 solution should offer better integration with other products."
"Talend Open Studio has a lot of capabilities, but there is some restriction. For example, if we want to connect to an SAP system, Open Studio cannot do it. We need to go with an enterprise version. Additionally, the monitoring features could improve."
"The security features could be improved."
"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."
"The user interface could be made simpler."
"The server-side should be completely revamped."
 

Pricing and Cost Advice

"The licensing should be improved, as the cost per connector is quite expensive."
"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 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."
"Depending on the size of the client you want to work with, it can be prohibitively expensive at times."
"I don't know the actual cost, but it's tens of thousands of dollars per month."
"Talking with my manager and others, nobody has complained about the pricing so far which is a positive sign."
"Denodo provides a lightweight 30-day free trial, but when we do courses on top of it, it costs $150 for each person."
"Right now, because we're using the open-source version, there's no cost."
"It is an open-source tool which means it is a free solution."
"The solution will be more expensive if you have a low data volume and a large number of developers."
"The paid version of this solution has a very high price, but even with the limitations, the Community version works fine."
"Price could be lower. It is getting too expensive when compared to some other solutions, which is actually a little bit concerning."
"Open Studio has a basic license and additional costs for services, including customer support and technical assistance."
"I am using the open-source version and it is free."
"It does the job well for nothing — without cost. That's the advantage of this product."
