Apache Druid is a distributed data processing system supporting real-time and multi-dimensional online analytical processing (OLAP). It is used to implement quick and interactive query and analysis for large data sets.
Characteristics of Apache Druid:
Druid is most frequently used for flexible, quick, multi-dimensional OLAP analysis on big data. In addition, as it supports ingestion of pre-aggregated data and analysis of aggregated data based on timestamps, it is usually used in time-series data processing and analysis, such as ad platform, real-time metric monitoring, recommendation model, and search model.
Druid uses a microservice-based architecture. All core services in it can be deployed on different hardware devices either separately or jointly.
