EGRES: A POSTGRES-COMPATIBLE DATABASE FOR HEAVY, MULTI-TENANT WORKLOADS

Summary from the TLDR Data newsletter

What would Postgres look like if designed today? Egres is the answer: a new open-source database that speaks the Postgres protocol but shares almost no Postgres code. It runs thousands of tenants in one process, metering CPU, memory, and disk per query, and its benchmark used 46% less disk than Postgres 18.
