CedarDBCedarDB

CedarDB is a relational database system that processes transactional and analytical workloads on a single engine. It runs any workload against the same, up-to-date data, without separate database systems or ETL pipelines to combine and synchronize the two. It is compatible with PostgreSQL's wire protocol and syntax, so existing applications and tools connect without application rewrites, and existing PostgreSQL data moves across with familiar tools including pg_dump, psql and Parquet imports.

The engine isolates analytics from concurrent writes with snapshot isolation and multi-version concurrency control: each reader operates on its own consistent view of the data while transactions continue in parallel, and operations that do not modify the database always succeed no matter how long they take. It is built for teams familiar with PostgreSQL that need fast analytics on live operational data, and because it is built from scratch rather than on PostgreSQL's internal codebase, arbitrary PostgreSQL extensions are generally not compatible.
