VIDARDB

Unlike most other databases that almost rely on a data structure designed in the 1970s, VidarDB is built on a revolutionary new Flexible Advanced Data Structure (FADS) that we invented for modern memory hierarchy, efficiently supporting RAM, NVMe, SSD, Disk as well as smooth data flow among these storage tiers... VidarDB is not only a storage engine, because it embeds deeply in PostgreSQL and reutilize PostgreSQL's many components, including SQL interface. Additionally, VidarDB has its own executor based on PostgreSQL's... Unlike general operational database, VidarDB is designed for modern memory hierarchy, with up to orders of magnitude faster in data ingestion and querying recent data. Fresh data sit in RAM first, and will be automatically flushed to secondary memory when RAM is full.
