With Impala, you can query data, whether stored in HDFS or Apache HBase – including SELECT, JOIN, and aggregate functions – in real time; Pachyderm: MapReduce without Hadoop. Analyze massive datasets with Docker. Pachyderm is an open source MapReduce engine that uses Docker containers for distributed computations.
Impala and Pachyderm belong to "Big Data Tools" category of the tech stack.
Some of the features offered by Impala are:
- Do BI-style Queries on Hadoop
- Unify Your Infrastructure
- Implement Quickly
On the other hand, Pachyderm provides the following key features:
- Git-like File System
- Dockerized MapReduce
- Microservice Architecture
Impala and Pachyderm are both open source tools. Pachyderm with 3.81K GitHub stars and 369 forks on GitHub appears to be more popular than Impala with 2.18K GitHub stars and 824 GitHub forks.
