YouTube

What are you trying to tell me? That I can read data fast? No, User. I'm trying to tell you that when you are ready, you won't have to. Everyone's heard about how fast Apache Iceberg and maybe you've even heard a few notes about "predicate pushdown" and "file metrics" but you've been left wanting more. You want to know... Read More

DBSP: Incremental Computation on Streams and Its Applications to Databases

Speaker:

Mihai Budiu

System:

Feldera

We describe DBSP, a framework for incremental computation. Incremental computations repeatedly evaluate a function on some input values that are "changing". The goal of an efficient implementation is to "reuse" previously computed results. Ideally, when presented with a new change to the input, an incremental computation should only perform work proportional to the size of the changes of the input,... Read More

Real-world Applications of Gen AI and Databases

Speaker:

Sailesh Krishnamurthy

System:

AlloyDB

In this talk we will explore the transformative potential of integrating databases and generative AI in enterprise applications. As Large Language Models (LLMs) are being rapidly adopted, it's clear that they need to interact with a plethora of other systems in the enterprise and agentic applications have emerged as the primary integration mechanism. Of these integration targets, databases are critical,... Read More

Architecture of Aerospike: Fast, Scalable, Geo-Replicated, Multi Model Database Supporting Strict Serializable Transactions

Speaker:

Srinivasan "Sesh" Seshadri

System:

Aerospike

Aerospike is a fast, scalable database that supports multiple data models such as a key value store with complex objects, graphs and vectors. Aerospike supports synchronous replication within a cluster to guarantee linearizability. It also supports asynchronous replication across clusters for disaster recovery with minimal overhead to normal transaction processing. Finally, Aerospike supports ACID transactions and guarantees strict serializability. In... Read More

[SQL Death] Gel: Replacing* SQL and Improving on the Relational Database Model

Speaker:

Michael Sullivan

System:

Gel

Video:

YouTube

Gel (formerly 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... Read More

[SQL Death] MariaDB’s Query Optimizer: A Multi-tool That Does Some Things Differently

Speaker:

Michael Widenius

System:

MariaDB

Video:

YouTube

MariaDB's query optimizer stems from MySQL's original implementation. It didn't come from a textbook, instead, it grew organically to meet the demands of the workloads we were targeting. This talk will discuss some of the uncommon choices we've made in MariaDB's new optimizer and what we've got (and lost) as a result. This talk is part of the SQL or... Read More

[SQL Death] OxQL: Oximeter Query Language

Speaker:

Ben Naecker

System:

OxQL

Video:

YouTube

Oxide Computer Company builds private cloud computers–co-designing hardware and software that works together. Our choice to own so much of the design was to enable systemic control and observability: we collect data from the smallest hardware sensor to the distributed control plane software. This talk covers the Oximeter Query Language (OxQL), the domain-specific language used to query and analyze this... Read More
