Data Architect at Devtech

Provides a consistent framework for building data integration and access solutions with reliable performance

The in-memory computation feature is certainly helpful for my processing tasks. It is helpful because while using structures that could be held in memory rather than stored during the period of computation, I go for the in-memory option, though there are limitations related to holding it in memory that need to be addressed, but I have a preference for in-memory computation. The solution is beneficial in that it provides a base-level long-held understanding of the framework that is not variant day by day, which is very helpful in my prototyping activity as an architect trying to assess Apache Spark, Great Expectations, and Vault-based solutions versus those proposed by clients like TIBCO or Informatica.

Data pipelines have run faster and support flexible batch and streaming transformations

We do not have any performance problems, but we do have some resource problems. Spark SQL consumes so many resources that we migrated our streaming job from Spark to Apache Flink. Resource management in Spark SQL should be better. It consumes more resources, which is normal. The main reason we switched from Spark is memory and CPU consumption. The major reason is the resource problem because the number of streaming jobs has been increasing in our company. That is why we considered resource management as a priority. Because of the resource consumption, I would say the development of Spark SQL is better. For development purposes, it is a top product and not difficult to work with, but resources are the major problem. We changed to Flink regardless of development time. Development time is less in Spark compared with Flink.

Quotes from Members

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

Pros

"The deployment of the product is easy."

"The data processing framework is good."

"Provides a lot of good documentation compared to other solutions."

"The scalability has been the most valuable aspect of the solution."

"One of the key features is that Apache Spark is a distributed computing framework. You can help multiple slaves and distribute the workload between them."

"I feel the streaming is its best feature."

"The distribution of tasks, like the seamless map-reduce functionality, is quite impressive."

"Aggregations are very fast in our project since we started to use Spark."

More Apache Spark pros

"The scalability of the solution is good."

"Overall the solution is excellent."

"The speed of getting data, as our TBs are big and it's a lot of data."

"Spark SQL's efficiency in managing distributed data and its simplicity in expressing complex operations make it an essential part of our data pipeline."

"The solution is easy to understand if you have basic knowledge of SQL commands."

"This solution is useful to leverage within a distributed ecosystem."

"The speed of getting data."

"Speed is the major benefit of using Spark SQL."

Cons

"Apache Spark provides very good performance The tuning phase is still tricky."

"I know there is always discussion about which language to write applications in and some people do love Scala. However, I don't like it."

"There could be enhancements in optimization techniques, as there are some limitations in this area that could be addressed to further refine Spark's performance."

"There were some problems related to the product's compatibility with a few Python libraries."

"From my perspective, the only thing that needs improvement is the interface, as it was not easily understandable."

"Like I said scalability is still an issue, also stability."

"The main problem is, now in the market, there are not many people certified in Apache Spark."

"Apache Spark is very difficult to use. It would require a data engineer. It is not available for every engineer today because they need to understand the different concepts of Spark, which is very, very difficult and it is not easy to learn."

More Apache Spark cons

"Being a new user, I am not able to find out how to partition it correctly."

"I've experienced some incompatibilities when using the Delta Lake format."

"It would be useful if Spark SQL integrated with some data visualization tools."

"The initial setup is a bit complex."

"There are many inconsistencies in syntax for the different querying tasks like selecting columns and joining between two tables so I'd like to see a more consistent syntax."

"It would be beneficial for aggregate functions to include a code block or toolbox that explains its calculations or supported conditional statements."

"It takes a bit of time to get used to using this solution versus Pandas as it has a steep learning curve."

"Being a new user, I am not able to find out how to partition it correctly. I probably need more information or knowledge. In other database solutions, you can easily optimize all partitions. I haven't found a quicker way to do that in Spark SQL. It would be good if you don't need a partition here, and the system automatically partitions in the best way. They can also provide more educational resources for new users."

More Spark SQL cons

Pricing and Cost Advice

"Apache Spark is not too cheap. You have to pay for hardware and Cloudera licenses. Of course, there is a solution with open source without Cloudera."

"Spark is an open-source solution, so there are no licensing costs."

"I did not pay anything when using the tool on cloud services, but I had to pay on the compute side. The tool is not expensive compared with the benefits it offers. I rate the price as an eight out of ten."

"It is an open-source platform. We do not pay for its subscription."

"We are using the free version of the solution."

"They provide an open-source license for the on-premise version."

"Apache Spark is an open-source tool."

"Apache Spark is open-source. You have to pay only when you use any bundled product, such as Cloudera."

More Apache Spark pricing and cost advice

"We don't have to pay for licenses with this solution because we are working in a small market, and we rely on open-source because the budgets of projects are very small."

"The solution is bundled with Palantir Foundry at no extra charge."

"The on-premise solution is quite expensive in terms of hardware, setting up the cluster, memory, hardware and resources. It depends on the use case, but in our case with a shared cluster which is quite large, it is quite expensive."

"We use the open-source version, so we do not have direct support from Apache."

"The solution is open-sourced and free."

"There is no license or subscription for this solution."
