Software Engineer at a tech vendor with 10,001+ employees
Automated data pipelines have transformed complex workloads and now deliver faster, reliable insight
The standout feature is the Data Awareness Engine, in my opinion the intelligent control plane. Unlike traditional orchestrators that run tasks based on schedules or external events, Ascend.io understands the state of the data. If a source file changes or transformation logic is updated, the engine automatically identifies only the impacted data partitions and recalculates exclusively those. This eliminated the need to write complex logic for partial reloads and ensures that downstream data is always consistent with the latest version of the code. Ascend.io impacted my organization positively because it helped me solve my problem by solving our operational maintenance crisis. Previously, every time a Spark job failed, we had to manually intervene to clean up partial data and restart the pipeline. With Ascend.io, infrastructure management and checkpointing are fully automated. It drastically reduced our technical debt, allowing our data engineers to focus on business logic rather than cluster management or writing boilerplate ingestion code. Code reduction eliminated 60% to 70% of custom Spark code. Operational cost saw a 30% reduction in man-hours dedicated to pipeline maintenance and incident management. The meantime to recovery reduced from hours to minutes due to automatic failure tracking. With Ascend.io, you write what you want, not how to do it. It is a declarative approach and reduces code by 80%. This is very important to me. A good feature is the integrated lineage because an instant visualization of data flow across all components is very useful.

Efficient data warehouse automation with robust features, but may require enhancements in user-friendly self-service options and pricing flexibility for broader corporate appeal
It could enhance its capabilities in the realm of self-service options as currently, it is more suited for individuals with technical proficiency who can create pages using it. When it comes to end users who may lack technical expertise, they are limited to toggling between existing developments. To empower end users to make critical changes without relying heavily on technical expertise, it would be beneficial to introduce more user-friendly features for development and modification. If it could incorporate correlation analysis capabilities into its platform, especially in a user-friendly manner, it would greatly enhance the tool's overall utility and make it an even more outstanding solution. There is a room for improvement regarding stability.

Pros

"With Ascend.io, infrastructure management and checkpointing are fully automated, drastically reducing our technical debt, allowing our data engineers to focus on business logic rather than cluster management or writing boilerplate ingestion code."
"One of the best features Ascend.io offers is Agentic analytics, which applies Agentic AI within systems to verify and operationalize data products, and it is live, allowing you to build systems and visualizations that turn data and different data sets into production-ready workflows."
"It is a scalable solution."
"It can scale."
"As long as you pick the solution that best fits with your requirements, you won't find that performance is a problem. It's good."
"Qlik Compose is good enough. It is user-friendly and intuitive."
"One of the most valuable features of this tool is its automation capabilities, allowing us to design the warehouse in an automated manner. Additionally, we can generate Data Lifecycle Policies (DLP) reports and efficiently implement updates and best practices based on proven design patterns."
"There were many valuable features, such as extracting any data to put in the cloud. For example, Qlik was able to gather data from SAP and extract SAP data from the platforms."
"It's a stable solution."
"The technical support is very good. I rate the technical support a ten out of ten."
 

Cons

"Ascend.io can be improved regarding the initial learning curve because for those used to writing pure Spark code, a mindset shift is required to trust the tool's automation."
"Ascend.io can be improved by perhaps expanding its reach beyond small industries to get into big industries or large investment companies and big financial industries, revolutionizing how data plays certain roles in leadership and decision-making."
"It would be better if the first level of technical support were a bit more technically knowledgeable to solve the problem. I think they could also improve the injection of custom scripts. It is pretty difficult to add additional scripts. If the modeling doesn't give you what you want, and you want to change the script generated by the modeling, it is a bit more challenging than in most other products. It is very good with standard form type systems, but if you get a more complicated data paradigm, it tends to struggle with transforming that into a model."
"There is some scope for improvement around the documentation, and a better UI would definitely help."
"I believe that visual data flow management and the transformation function should be improved."
"I don't think Qlik can be used in a high-volume scenario. It didn't work for us."
"My issues with the solution's stability are owing to the fact that it has certain bugs causing issues in some functionalities that should be working."
"There should be proper documentation available for the implementation process."
"When processing data from certain tables with a large volume of data, we encounter significant delays. For instance, when dealing with around one million records, it typically takes three to four hours. To address this, I aim to implement performance improvements across all tables, ensuring swift processing similar to those that are currently complete within seconds. The performance issue primarily arises when we analyze the inserts and updates from the source, subsequently dropping the table. While new insertions are handled promptly, updates are processed slowly, leading to performance issues. Despite consulting our Qlik vendors, they were unable to pinpoint the exact cause of this occurrence. Consequently, I am seeking ways to optimize performance within Qlik Compose, specifically concerning updates."
"There could be more customization options."
