Open discussion session on synchronisation for quantum communication / Serrano, Javier (speaker) (CERN)
The conference at CERN will be a unique opportunity to have a discussion among key actors in synchronisation for quantum communication: What is missing in the domain of synchronisation for quantum communication? - Precision/accuracy needs. - User interface: providing and time-stamping pulses, bursts, etc. Controlling times, repetition rates, duty cycles… - Distance requirements - Combining or not quantum and classical networks in the same fibre - Opportunities for standardisation, formal or de-facto - Other? What are your plans for the short and medium term? Can this event spawn one or more collaborative efforts in this domain? Please write to us at qti@cern.ch with your initial thoughts so we can put in place a plan for this session, including moderation, and make the best use of our valuable time together [...]

From Queries to Pints: Building a Beer Recommendation System with pgvector / Nowicki, Andrzej (speaker) (CERN)
Discover how easily you can create a recommendation system from scratch using modern AI and database technologies. In this session, we’ll build a beer recommendation system using advanced language models and PostgreSQL’s pgvector extension. By leveraging the capabilities of pgvector, we can seamlessly store high-dimensional embeddings generated from beer descriptions and perform similarity search with user preferences. Whether you’re a seasoned database administrator or just starting to explore the potential of AI, this presentation will equip you with practical insights and hands-on techniques to integrate machine learning into your database workflows. [...]

Harnessing Postgres and HPC for Petabyte-Scale Variable Star Classification in Astronomy / Nienartowicz, Krzysztof (speaker) (Sednai) ; Krefl, Daniel (speaker) (Sednai)
In this talk, we will showcase our use of a Massively Parallel Postgres Database as a petabyte-scale astronomical datastore, powering variable star analysis for the ESA Gaia space telescope. Our presentation will also highlight two Postgres extensions developed in-house: a new Postgres-to-Java interface and a GPU-accelerated vector index. [...]

Anatomy of Table-Level Locks in PostgreSQL / Yildirim Jelinek, Gulcin (speaker)
**Short abstract** Understanding table-level locks in Postgres is a quite useful skill as almost all DDL operations require acquiring one of the different types of table-level locks on the object being manipulated. If not managed well, schema changes can result in downtime. [...]

Maximising Microservice Databases with Kubernetes, Postgres, and CloudNativePG / Cecchi, Leonardo (speaker) ; Bartolini, Gabriele (speaker)
As a developer, you may follow continuous delivery practices yet treat your database as an external component, introducing risks with changes and migrations. It's time to change that by embracing microservice databases within your organisation. This talk explores how PostgreSQL and Kubernetes, through CloudNativePG, can help you establish a seamless, open-source, vendor-neutral microservice database environment. [...]
