Synergy: Teamwork Makes the Dream Work

presented by Zak Tedder

Communication in the Tech world can be brutal. People are busy and things need to get done. All the tasks and moving parts can make it difficult to see the end goal or how it all comes together. This can also foster a very competitive environment, where Pug-eat-Pug and the last Frenchy standing wins the prize. However, there is a much faster and solid route to the goal: synergy.

Frank McSherry Enabling New Operational Use Cases with PostgreSQL

presented by Frank McSherry

As the world moves towards lower latency in operational workloads, a new opportunity is emerging for database architects to ask which query processing work in their database should be performed proactively, as data change, and which work should be performed reactively, as queries roll in. Naturally, to do this you will need a tool that integrates seamlessly with PostgreSQL and maintains your qu...

Denis Magda PgCompute: Creating Stored Procedures the Developer Way

presented by Denis Magda

Stored procedures have been a feature of Postgres for years. They were designed to let developers execute data or compute-intensive logic directly where the data lives—in the database—thereby reducing network latency. However, even in 2024, this relational database feature hasn’t gained widespread adoption within developer communities for various reasons.

PgCompute is a new client-side Postg...

What is the difference between your stable production and test databases? Data.

When your system is active, data changes very quickly. You have made a backup up, and the next hour, it won't match with the database anymore. You migrated the data from your old database to a new one, but while you are finalizing all processes, data stops being synchronized. Of course, you can compare the data ...

Gwen Shapira Transaction Isolation in Postgres
Understand transaction isolation levels once and for all with many examples and a bit of history

presented by Gwen Shapira

Transactions are a key part to many modern databases, relational and non-relational systems alike. At a basic level, transactions allow us to treat a series of operations as a single unit. The reason transactions are so important is because they provide guarantees that developers can then use as assumptions when writing code. This means that there are entire set of concerns that you, the develo...
