CrateIO vs Hadoop: What are the differences?
What is CrateIO? The Distributed Database for Docker. Crate is a distributed data store. Simply install Crate directly on your application servers and make the big centralized database a thing of the past. Crate takes care of synchronization, sharding, scaling, and replication even for mammoth data sets.
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.
CrateIO and Hadoop can be primarily classified as "Databases" tools.
"Simplicity" is the top reason why over 2 developers like CrateIO, while over 34 developers mention "Great ecosystem" as the leading cause for choosing Hadoop.
CrateIO and Hadoop are both open source tools. It seems that Hadoop with 9.26K GitHub stars and 5.78K forks on GitHub has more adoption than CrateIO with 2.49K GitHub stars and 333 GitHub forks.

Since the beginning, Cal Henderson has been the CTO of Slack. Earlier this year, he commented on a Quora question summarizing their current stack.
Apps- Web: a mix of JavaScript/ES6 and React.
- Desktop: And Electron to ship it as a desktop application.
- Android: a mix of Java and Kotlin.
- iOS: written in a mix of Objective C and Swift.
- The core application and the API written in PHP/Hack that runs on HHVM.
- The data is stored in MySQL using Vitess.
- Caching is done using Memcached and MCRouter.
- The search service takes help from SolrCloud, with various Java services.
- The messaging system uses WebSockets with many services in Java and Go.
- Load balancing is done using HAproxy with Consul for configuration.
- Most services talk to each other over gRPC,
- Some Thrift and JSON-over-HTTP
- Voice and video calling service was built in Elixir.
- Built using open source tools including Presto, Spark, Airflow, Hadoop and Kafka.
- For server configuration and management we use Terraform, Chef and Kubernetes.
- We use Prometheus for time series metrics and ELK for logging.
HadoopThe MapReduce workflow starts to process experiment data nightly when data of the previous day is copied over from Kafka. At this time, all the raw log requests are transformed into meaningful experiment results and in-depth analysis. To populate experiment data for the dashboard, we have around 50 jobs running to do all the calculations and transforms of data.
Hadoopin 2009 we open sourced mrjob, which allows any engineer to write a MapReduce job without contending for resources. Weโre only limited by the amount of machines in an Amazon data center (which is an issue weโve rarely encountered).
HadoopThe massive volume of discovery data that powers Pinterest and enables people to save Pins, create boards and follow other users, is generated through daily Hadoop jobs...
