Apache Druid
A high performance, real-time analytics database for sub-second queries

Apache Druid is an open-source, high-performance real-time analytics database designed for OLAP queries on large-scale streaming and batch data. It supports sub-second query responses on datasets with billions to trillions of rows, with native integrations for Apache Kafka and Amazon Kinesis. Druid is built for high-concurrency workloads and features elastic architecture, automatic data optimization, and SQL support.
Druid ingests streaming and batch data, automatically columnarizes and indexes it, and uses a scatter/gather query engine with data preloaded into memory or local storage for ultra-fast OLAP queries.
