CrateDB is a SQL, open-source, distributed database that makes storage and analysis of massive amounts of data simple and efficient. It offers effective data handling due to a high degree of scalability and availability, real-time query performance, and extensible data models. In this talk, we will discuss the fundamental concepts of CrateDB and highlight what makes it unique in comparison... Read More

We built SplinterDB to address two trends. The first is the modern storage hardware offers significantly higher bandwidth and lower latency. The second is that modern applications at VMware and elsewhere store fine-grain data, such as metadata. Current state-of-the-art key-value stores such as RocksDB fail to fully exploit the capabilities of these devices on these types of workloads. SplinterDB is... Read More

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
