The sled embedded database is generally regarded as an “ok” choice for working with embedded data in an ergonomic, too-fast-for-its-own-good, transactional manner. But it wasn’t always that way! This talk covers the motivations, design choices, mistakes, and evolution during the first 6 years of this young database’s life. Topics covered: lock-free index structures, low-overhead logging, cheap OLTP transaction techniques, the... Read More

Greenplum is an established large scale data-warehouse system with both enterprise and open-source deployments. The massively parallel processing (MPP) architecture of Greenplum splits the data into disjoint parts that are stored across individual worker segments. The increased amount of data these systems have to process magnifies optimization mistakes and stresses the importance of query optimization more than ever. Furthermore, there... Read More

Azure Cosmos DB is a multi-tenant globally distributed database service for managing JSON documents at Internet scale. As the amount of data managed by the service has grown several times over the past 5 years, customers have shown an increasing need for being able to do efficient analytics on top of this operational data store. The customer asks include: reducing... Read More

In this talk, we will walk through the architecture and implementation of SpiceDB, an open-source permissions database. As an implementation of Google’s Zanzibar (the singular global-scale authorization service that powers permissions and sharing across all Google properties) paper, he will focus heavily on facets of the database that allow it to run highly scalably, with low latency and incredible reliability....

In this talk, Oren Eini, founder of RavenDB, will discuss the design decisons and the manner in which RavenDB deals with storing data on disk. Achieving highly concurrent and transactional system can be a challenging task. RavenDB solves this issue using a storage engine called Voron. We'll go over the design of Voron and how it is able to achieve... Read More

Data-driven companies are increasingly building customer-facing analytics products. These workloads demand lower latency, higher concurrency, and more predictable query performance than ever before - demands that traditional data warehouses struggle with. In this talk, Benjamin explains how Firebolt is designed to welcome this new generation of data challenges. This talk is part of the Vaccination Database (Second Dose) Tech Talk... Read More

Apache Arrow is a multi-language toolbox for accelerated data interchange and in-memory processing. With the aim to make the data ecosystem modular and connected, Wes will talk about Apache Arrow’s vision for a future more unified data analytics ecosystem. In this talk, Wes will discuss the underlying interfaces and protocols powering the project, trends in the Apache Arrow ecosystem, and... Read More

Google BigQuery is a serverless, scalable, and cost effective cloud data warehouse. Having evolved from internal Google infrastructure (Dremel), BigQuery is unique in a number of dimensions. In this talk, we provide a look at some of the key architectural aspects of BigQuery and how it provides a true serverless and multi-tenant warehousing solution to customers. We then provide an...

Many of us have devoted decades of our lives to making databases faster, cheaper, more scalable, more reliable... much of which is completely irrelevant to the average developer. The main obstacle for the next generation of app developers is convenience. The "serverless revolution" and architectures like Jamstack demonstrate a desire for life without a backend team, yet current technologies in... Read More
