pgrust
Postgres rewritten in Rust, now passing 100% of the Postgres regression tests
Explore how pgrust implements logical and physical replication using the CopyBoth API. Discover type-safe Rust methods for seamless data streaming and slot management.
How pgrust Implements Locking and LWLock: PostgreSQL Concurrency Primitives in RustDiscover how pgrust implements PostgreSQL locking and LWLock using Rust abstractions. Learn about safe concurrency primitives and RAII guard types for shared memory coordination.
How pgrust Manages User-Defined Types and Domains: A Deep Dive into the Type Cache SystemDiscover how pgrust manages user-defined types and domains using a centralized type cache system and specialized modules. Learn about constraint validation and I/O operations.
How Vacuum and Autovacuum Operations Work in pgrustExplore how pgrust implements PostgreSQL vacuum and autovacuum in Rust. Understand heap_vacuum_rel, cost-delay, and eager-freeze for efficient database maintenance.
Connection Handling and Postmaster Architecture in pgrust: A Deep Dive into the Rust PostgreSQL ImplementationExplore pgrust's connection handling and postmaster architecture, a Rust port of PostgreSQL's model. Understand how the master process manages backends for client requests.
How pgrust Handles Prepared Statements and Portals: PostgreSQL's Two-Stage Model in RustLearn how pgrust implements PostgreSQL's prepared statements and portals in Rust. Discover safe Rust seams for query planning and execution contexts.
How the COPY Command Works in pgrust: Protocol Implementation and Data StreamingExplore the pgrust COPY command's protocol implementation and data streaming. Understand frontend/backend message handling and PostgreSQL's bulk data transfer.
