In the realm of big data analytics, Apache Doris and Elasticsearch stand out as popular choices for real-time analytics and retrieval tasks. Nevertheless, their distinct design principles and technical emphases set them apart. Let’s delve into a comprehensive comparative analysis across various dimensions to shed light on their differences and strengths.
Core Design Philosophy: MPP Architecture vs. Search Engine Architecture
When it comes to core design philosophy, Apache Doris adopts a Massively Parallel Processing (MPP) distributed architecture. This design, as detailed in a DZone article, is finely tuned for high-concurrency, low-latency real-time Online Analytical Processing (OLAP) scenarios. With front-end and back-end components working in tandem, Doris harnesses multi-node parallel computing and columnar storage to effectively handle vast datasets. This architecture empowers Doris to swiftly provide query results in mere seconds, rendering it especially adept at intricate aggregations and analytical queries on extensive data sets.
