Hadoop vs Redis: What are the differences?
What is Hadoop? Open-source software for reliable, scalable, distributed computing. The Apache Hadoop software library is a framework that allows for the distributed processing of large data sets across clusters of computers using simple programming models. It is designed to scale up from single servers to thousands of machines, each offering local computation and storage.
What is Redis? An in-memory database that persists on disk. Redis is an open source, BSD licensed, advanced key-value store. It is often referred to as a data structure server since keys can contain strings, hashes, lists, sets and sorted sets.
Hadoop and Redis are primarily classified as "Databases" and "In-Memory Databases" tools respectively.
"Great ecosystem" is the primary reason why developers consider Hadoop over the competitors, whereas "Performance" was stated as the key factor in picking Redis.
Hadoop and Redis are both open source tools. It seems that Redis with 37.1K GitHub stars and 14.3K forks on GitHub has more adoption than Hadoop with 9.18K GitHub stars and 5.74K GitHub forks.
reddit, Instacart, and Slack are some of the popular companies that use Redis, whereas Hadoop is used by Slack, Shopify, and SendGrid. Redis has a broader approval, being mentioned in 3239 company stacks & 1732 developers stacks; compared to Hadoop, which is listed in 237 company stacks and 116 developer stacks.
