TigerBeetle is an open source distributed financial accounting database designed for mission critical safety and performance to track financial transactions at scale. TigerBeetle is coded to NASA’s Power of Ten Rules for Safety Critical Code. All memory is statically allocated at startup for predictable and efficient resource usage. Function arguments and return values are verified at runtime by over three... Read More

GAIA database is an unusual engine - it offers a direct access model and supports memory pointers, applications are able to create and navigate complex data structures like graphs with no or very little API overhead: the engine implements transactional memory view with full transactional durability - whatever you do in memory gets captures and persistent in an efficient transparent...

EdgeDB is a new database built around an evolution of the relational model that we call "graph-relational". In the graph-relational model, data is represented as strongly typed objects containing set-valued scalar properties and links to other objects. Missing values are represented in the language as empty sets (no NULL!), and have consistent semantics. The query language, EdgeQL, supports convenient fetching... Read More

RisingWave is a cloud-native streaming database. Different from existing streaming systems, RisingWave fully leverages the modern cloud infrastructure to achieve high performance and scalability at a low cost. In this talk, I will walk you through the detailed designs of RisingWave, and discuss how we adopt some old ideas to build a next-generation streaming system. This talk is part of... Read More

OceanBase Database, is an open-source, distributed Hybrid Transactional/Real-time Operational Analytics (HTAP) database management system that has set new world records in both the TPC-C and TPC-H benchmark tests. OceanBase Database starts from 2010, and it's built from scratch by Alibaba & Ant Group, it provides features of an enterprise-level database, including the native distributed architecture, financial-grade high availability, transparent horizontal...

Neon is a Postgres cloud service that separates compute and storage. Separation of compute and storage makes it possible to scale the components independently, and instant startup without a lengthy restore. Amazon Aurora pioneered the separation of compute and storage for OLTP databases. Neon uses the same concept of applying the WAL stream to reconstruct database state in the storage... Read More

SQLite has long been regarded as an incredibly reliable, fast, & easy-to-use database in the world of personal devices such as laptops & phones. However, it's never gained much traction in the world of web applications because it's built as a single-node database. Litestream adds simple, cheap streaming replication to SQLite to expand the use cases that the database can... Read More

In hypertext world connection proxies is a must for many decades now. And in many cases this idea works for databases too! Today almost any busy OLTP Postgres instance have to use some sort of proxy: old but gold PgBouncer, scalable Odyssey or entirely new SPQR\PgCat. In this talk I'll discuss what allows proxies to be useful, what Postgres hackers... Read More

Why settle for 1 cool db talk when you can get 3? Snowflake is pushing the boundaries of what a unified cloud data platform can do. Today we'll talk about how Snowflake can be combined with open standards like Apache Iceberg, hard tech to stream data into Snowflake and bring transactional and analytical workloads together in a single platform. Apache... Read More
