Featured Reviews

Kunal Shah - PeerSpot reviewer
Senior Business Intelligence Developer at VodafoneZiggo
Standardized ELT templates have accelerated delivery while API and UI flexibility still need improvement
The best features Coalesce.io offers in my experience include lineage, which is the most important from the Ziggo perspective, and the APIs, which I would rank as the second most valuable. The third feature is the bulk edit option, so we don't have to do repetitive tasks again and again. The new SQL feature they are introducing, where you can dump your SQL and have your table or view created without manually creating columns, is also valuable. These are the four features I appreciate the most, and the fifth one would be the recently implemented GUI change where you can put a node in a spotlight to see the upstream and downstream based on what you need, setting up the depth and those settings. Coalesce.io has positively impacted my organization by reducing our development time and the time to market from around 15 days to a couple of days. This is the biggest impact we have experienced, and we are able to enforce a standardized way of working among developers, eliminating silos or customized solutions that developers create for themselves. If a satellite is loaded by ten different processes, all ten different processes generate the same type of SQL, making it easier to debug later if someone new joins the team. Additionally, since it is a SaaS solution, there is no need to maintain any software or install anything on laptops, which has helped us at VodafoneZiggo. Another feature is the API feature and the CLI command tool, which aid us significantly in moving from PowerCenter to Coalesce, enabling the migration of mappings from PowerCenter to Coalesce in bulk.

Advanced features enhance business intelligence, but complex management calls for improved user guidance
While my experience with IBM Db2 Warehouse is somewhat limited, when compared to other databases such as Oracle, there are areas for improvement. They need to enhance the database to make it more user-friendly and easier to master. They should implement a more comprehensive graphical user interface with additional features. For instance, when users encounter problems, the system should provide better guidelines and troubleshooting directions, except for hardware-related issues. They need to implement tools that would help users perform basic troubleshooting rather than solely relying on support. Other databases have features where users can investigate specific issues using error codes. From my experience, many minor issues could be resolved before escalating to support.

Quotes from Members

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

Pros

"Coalesce.io has positively impacted my organization by making development faster and keeping the logic clearer, so we do not have to see 1000-2000 lines of code every time."
"Coalesce.io has positively impacted my organization by being a tool that can be leveraged by a non-technical team, especially business analysts who are working on bringing data from different sources."
"The best features that Coalesce.io offers include a very rigid ETL framework that ensures all developers use the same pattern."
"Coalesce.io has impacted our organization positively by providing a low-code approach, supporting different sources so we don't need to write custom code, and offering a collaborative tool suitable for teams with a large number of developers."
"Usually it takes six to seven weeks to develop all those things, but with Coalesce.io, I can complete those things in one week."
"Coalesce.io has helped me develop projects faster, as it is easy to implement and maintain, reducing execution time by thirty to forty percent, while also helping me design a modular approach."
"Coalesce.io has positively impacted my organization by improving workflow, productivity, and business outcomes."
"Using Coalesce.io, I have reduced my transformation process and eliminated macros that were previously used, creating reusable programs that are helpful for other projects and models, which has reduced code dependencies between teams and saved approximately three hundred to four hundred dollars per day in processing costs."
"It's easy and practical to use."
"The initial setup was really easy; it's Docker compliant, you just pull the image from the IBM repository and that's it, and the deployment must have taken less than an hour, making it really fast to have it completely working."
"The solution works with big data, so it's pretty scalable."
"I think it scales really well and as long as you take enough time to learn a little bit about it, it works really well."
"It can scale effectively as long as resources are available."
"Some of the best features are stored procedures, parallelism, and different indexing strategies."
"IBM Db2 Warehouse is more resilient when dealing with business intelligence applications."
"The solution is stable."
 

Cons

"I do not find anything particularly helpful or something that stands out yet."
"Coalesce.io could improve in their AI features that they have enabled now."
"Coalesce.io can be improved regarding the APIs that still do not support all types of scenarios within a node, which is a blocking issue for us and potentially for other companies as well."
"I believe the editing should be a bit easier, or there should be a bulk edit option where a column can be added in one go in multiple places."
"Coalesce.io is compatible with Snowflake only, so it must be configured with other platforms such as Databricks and BigQuery, which is a limitation and a drawback."
"For that specific use case, I was able to accomplish what I was trying to do during the demo, but we encountered certain scenarios such as post-hooks, update statements, edge cases, or particular SQL query modifications and custom cases that could not be implemented through the GUI interface."
"Coalesce.io could be improved from the stage layer perspective."
"At the moment, the only improvement I see is deeper support for AI agents to support the developer's job."
"There were some initial challenges with IBM Db2 Warehouse about eight months ago when I worked in this environment. When I coordinated with IBM support, they mentioned that the memory was insufficient for our needs. Our business environment required significantly more memory than the previous cluster could provide. Consequently, we have worked closely with on-site IBM technical personnel to address this issue."
"The primary challenges customers face with IBM Db2 Warehouse are related to its complexity in usage. It requires highly skilled professionals who understand Db2, and both training and support are challenging to obtain."
"Lacks sufficient documentation and particularly in Spanish."
"Responding to support tickets takes a lot of time. It can range from two to four days, even for critical issues."
"The biggest problems we have is when the backup solution is failing or slow and we run out of log space, which has happened probably a couple of times in the last four years."
"On a scale of one to ten, I would rate the technical support as a five. It is fairly bad."
"The areas of the solution that is needing the most improvement are separating compute from storage, elasticity, which means scaling up and then retracting."
"The biggest challenge anyone could have with Db2 Warehouse is their references or online resources and documentation. They are very, very, very limited on the web."
