Apache Spark vs Apache Ignite [closed]

Question

Currently I'm studying Apache spark and Apache ignite frameworks.

Some principle differences between them are described in this article ignite vs spark But I realized that I still don't understand their purposes.

I mean for which problems spark more preferable than ignite and vice versa?

Answer 1

I would say that Spark is a good product for interactive analytics, while Ignite is better for real-time analytics and high performance transactional processing. Ignite achieves this by providing efficient and scalable in-memory key-value storage, as well as rich capabilities for indexing, querying the data and running computations.

Another common use for Ignite is distributed caching, which is often used to improve performance of applications that interact with relational databases or any other data sources.
