Reliable, able to expand, and handle large amounts of data well
Pros and Cons
  • "There's a lot of functionality."
  • "It's a nice system for batch processing huge data."
  • "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."
  • "They currently use a JDK version which is a little bit old. Not all features are on it."

What is our primary use case?

It's a root product that we use in our pipeline.

We have some input data. For example, we have one system that supplies some data to MongoDB, for example, and we pull this data from MongoDB, enrich this data from other systems - with some additional fields - and write to S3 for other systems. Since we have a lot of data, we need a parallel process that runs hourly.

What is most valuable?

We use batch processing. It works well with our formats and file versions. There's a lot of functionality. 

In our pipeline each hour, we make a copy of data from MongoDB, of the changes from MongoDB to some specific file. Each time pipeline copied all of the data, it would do it each time without changes to all of the tables. Tables have a lot of data, and in the last MongoDB version, there is a possibility to read only changed data. This reduced the cost and configuration of the cluster, and we saved about $150,000.

The solution is scalable.

It's a stable product.

What needs improvement?

The primary language for developers on Spark is Scala. Now it's also about Java. I prefer Java versus Scala, and since they are supported, it is good. 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.

They use currently have a JDK version which is a little bit old. Not all features are on it. Maybe they should pull support of the JDK version.

For how long have I used the solution?

I've used the solution for a year and a half.

What do I think about the stability of the solution?

The solution is stable. There are no bugs or glitches. It doesn't crash or freeze. 

What do I think about the scalability of the solution?

The product scales well. It's fine to expand if needed. 

Many teams use Spark. For example, we have a few kinds of pipelines, huge pipelines. One of them processes 300 billion events each day. It's our core technology currently.

We do not plan to increase usage. We keep our legacy system on Spark, and we are now discussing Flink and Spark and what we would prefer. However, most of the people are already migrating new systems to Flink. We will keep Spark for a few more years still. 

How are customer service and support?

We have an internal team, and they participate in process of developing Spark. They are Spark contributors, and if we have some problems, we turn to them. It's our own people, yet they work with Spark. Generally, if the problem is more minor, we look at some sites or have some discussion about Spark or internal guys who have experience with Spark. 

Which solution did I use previously and why did I switch?

We also use Flink.

Before Spark, I worked with another company that we used some different technology, including Kafka, Radius, Postgres SQL, S3, and Spring. 

How was the initial setup?

I didn't handle the initial setup. We were using this pipeline and clusters already. I just installed it on my local server. However, in terms of difficulty, I didn't see any problem. The deployment might only take a few hours. 

I found some documentation. I got the documentation from the site and downloaded the archive and unzipped it, and installed it. I can't say that I installed something from a special configuration. I just installed a few nodes for debugging and for running locally, and that's all. Also, in one case I used, for example, a Docker configuration with Spark. It all worked fine.

What's my experience with pricing, setup cost, and licensing?

It's an open-source product. I don't know much about the licensing aspect. 

Which other solutions did I evaluate?

We have compared Flink and Spark as two possible options. 

What other advice do I have?

I can recommend the product. It's a nice system for batch processing huge data.

I'd rate the solution eight out of ten.

Seamless in distributing tasks, including its impressive map-reduce functionality
Pros and Cons
  • "The distribution of tasks, like the seamless map-reduce functionality, is quite impressive."
  • "When using Spark, users may need to write their own parallelization logic, which requires additional effort and expertise."

What is our primary use case?

Predominantly, I use Spark for data analysis on top of datasets containing tens of millions of records.

How has it helped my organization?

I have an example. We had a single-threaded application that used to run for about four to five hours, but with Spark, it got reduced to under one hour.

What is most valuable?

The distribution of tasks, like the seamless map-reduce functionality, is quite impressive. For the user, it appears as simple single-line data manipulations, but behind the scenes, the executor pool intelligently distributes the map and reduce functions.

What needs improvement?

The visualization could be improved.

For how long have I used the solution?

I have been working with Apache Spark for only a few months, not too long.

What do I think about the stability of the solution?

I haven't faced any stability issues. It has been stable in my experience.

What do I think about the scalability of the solution?

When it comes to the scalability of Spark, it's primarily a processing engine, not a database engine. I haven't tested it extensively with large record sizes.

In my organization, quite a few people are using Spark. In my smaller team, there are only two users.

What about the implementation team?

In terms of maintenance, when the load hits around 95%, we need to prioritize scripts and analysis within the team. 

We coordinate and prioritize based on the available resources. If there were self-service tools or better hand-holding for such situations, it would make things easier.

Which other solutions did I evaluate?

Currently, we extensively use pandas and Polaris. We are leveraging Docker and Kubernetes as a framework, along with AWS Batch for distribution. This is the closest substitute we have for Spark Distribution.

Both Docker and Kubernetes are more general-purpose solutions. If someone is already using Kubernetes and it's provided as a service, it can be used for special-purpose utilization, similar to Docker and Kubernetes.


In such cases, users may need to write the parallelization logic themselves, but it's relatively easy to onboard and start with a distributed load. Spark, on the other hand, is primarily used for special-purpose utilization. Users typically choose Spark when they have data-intensive tasks.

Another significant issue with Spark is its syntactics. For instance, if we have libraries like Panda or Polaris, we can run them single-threaded on a single core, or we can distribute them leveraging Kubernetes.

We don't need to rewrite that code base for Spark. However, if we are writing code specifically for Spark Executors, it will not be amenable to running it locally.

What other advice do I have?

I would recommend understanding the use case better. Only if it fits your use case, then go for it. But it is a great tool.

Overall, I would rate Apache Spark an eight out of ten.

High performance, beneficial in-memory support, and useful online community support
Pros and Cons
  • "One of Apache Spark's most valuable features is that it supports in-memory processing, the execution of jobs compared to traditional tools is very fast."
  • "Apache Spark could improve the connectors that it supports. There are a lot of open-source databases in the market. For example, cloud databases, such as Redshift, Snowflake, and Synapse. Apache Spark should have connectors present to connect to these databases. There are a lot of workarounds required to connect to those databases, but it should have inbuilt connectors."
  • "Apache Spark could improve the connectors that it supports."

What is our primary use case?

Apache Spark is a programming language similar to Java or Python. In my most recent deployment, we used Apache Spark to build engineering pipelines to move data from sources into the data lake.

What is most valuable?

One of Apache Spark's most valuable features is that it supports in-memory processing, the execution of jobs compared to traditional tools is very fast.

What needs improvement?

Apache Spark could improve the connectors that it supports. There are a lot of open-source databases in the market. For example, cloud databases, such as Redshift, Snowflake, and Synapse. Apache Spark should have connectors present to connect to these databases. There are a lot of workarounds required to connect to those databases, but it should have inbuilt connectors.

For how long have I used the solution?

I have been using Apache Spark for approximately five years.

What do I think about the stability of the solution?

Apache Spark is stable.

What do I think about the scalability of the solution?

I have found Apache Spark to be scalable.

How are customer service and support?

Apache Spark is open-source, there is no team that will give you dedicated support, but you can post your queries on the community forums, and usually, you will receive a good response. Since it's open-source, you depend on freelance developers to respond to you, you cannot put a time limit there, but the response, on average, is pretty good.

How was the initial setup?

If Apache Spark is in the cloud, setting it up will require only minutes. If it's on Amazon, GCP, or Microsoft cloud, it'll take minutes to set everything up. However, if you are using the on-premise version, then it might take some time to set up the environment.

What other advice do I have?

I rate Apache Spark an eight out of ten.

Which deployment model are you using for this solution?

Public Cloud

If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?
