Apache Accumulo is a distributed key/value store designed for robust and scalable data storage and retrieval. It utilizes Apache Hadoop's HDFS for data storage and Apache ZooKeeper for consensus management. Accumulo allows users to manage large datasets across clusters and supports server-side programming through a mechanism called Iterators, which can modify key/value pairs during data management. It features cell-based access control, where each key/value pair has a security label that restricts query results based on user authorizations. The system is designed to scale, allowing nodes to be added or removed as data storage needs change. Accumulo maintains a stable client API that adheres to long-term maintenance (LTM) releases and semantic versioning, with each release undergoing extensive testing. The latest versions include Accumulo 3.0.0 and 2.1.3, with a preview of version 4.0 expected in October 2024.
