  3. Apache ZooKeeper

    Apache ZooKeeper

    Project mention: Mastering Apache Kafka: Powering Modern Data Pipelines | dev.to | 2025-01-16

    Zookeeper is a distributed coordination service used in older versions of Kafka to manage cluster metadata, leader election, and configuration. It ensures consistency and synchronization across Kafka brokers.

  4. Trino

    Official repository of Trino, the distributed SQL query engine for big data, former

    Project mention: Apache Iceberg | news.ycombinator.com | 2025-01-25

  5. starrocks

    The world's fastest open query engine for sub-second analytics both on and off the data lakehouse. With the flexibility to support nearly any scenario, StarRocks provides best-in-class performance for multi-dimensional analytics, real-time analytics, and ad-hoc queries. A Linux Foundation project.

    Project mention: A MySQL compatible database engine written in pure Go | news.ycombinator.com | 2024-04-09

    tidb has been around for a while, it is distributed, written in Go and Rust, and MySQL compatible. https://github.com/pingcap/tidb

    Somewhat relatedly, StarRocks is also MySQL compatible, written in Java and C++, but it's tackling OLAP use-cases. https://github.com/StarRocks/starrocks

  6. Crate

    CrateDB is a distributed and scalable SQL database for storing and analyzing massive amounts of data in near real-time, even with complex queries. It is PostgreSQL-compatible, and based on Lucene.

    Project mention: OpenAI Acquires Rockset | news.ycombinator.com | 2024-06-21

    Great initiative making a list of possible Rockset replacements. Would it be possible to open the Notion page for guest contributions?

    I would like to add CrateDB (I work there) to the list. CrateDB is a distributed SQL database purposely built for real-time analytics across large datasets of structured and semi-structured data. Similarly to Rockset, it indexes all data in real-time (text, vector, geospatial, time-series, and JSON) for the most efficient search and fast ad hoc query execution at any scale. It is built on top of Apache Lucene and unlike Rockset is open-source (https://github.com/crate/crate).

    Rocket frequently comes up among other solutions our users were looking at before choosing CrateDB. For example https://cratedb.com/customers/govspend.

  7. scalardb

    Universal HTAP Engine

  8. herddb

    A JVM-embeddable Distributed Database

  10. kronotop

    Kronotop is a distributed and transactional document database backed by FoundationDB.

    Project mention: Kronotop: Redis-compatible, transactional document store backed by FoundationDB | news.ycombinator.com | 2025-01-20

  11. Serengeti

    Serengeti - The Autonomous Distributed Database
