    rethinkdb

    27Krethinkdb/rethinkdb · C++

    17.3Ktursodatabase/libsql · C

    libSQL is an open-source fork of SQLite with open contributions: the same embeddable SQL database, extended with features like embedded replicas and remote access, while staying compatible with SQLite.

    electric

    10.4Kelectric-sql/electric · TypeScript

    Electric is a real-time sync engine for Postgres: it replicates data out of your database into anything — web apps, mobile clients, AI agents — handling the hard parts like partial replication, fan-out and data delivery.

    The-Accidental-CTO

    3.9Ksubhashchy/The-Accidental-CTO · TypeScript

    This is 'The Accidental CTO', a story-driven system design handbook by Subhash Choudhary about scaling the Dukaan e-commerce platform from zero to over a million stores without a formal CS degree.

    kafgres

    417RayElg/kafgres · Rust

    kafgres is a PostgreSQL extension that embeds a full Kafka broker inside Postgres: unmodified Kafka clients connect on port 9092 and Postgres stores all topics, partitions, offsets, and the log itself, giving transactional coupling between the database and the event stream.

    walshadow

    242ClickHouse/walshadow · Rust

    walshadow replicates PostgreSQL rows into ClickHouse by reading the physical WAL — initial load, continuous changes, schema evolution, restarts, and planned source switchover are all part of the flow.
