Spoke at @PGConfIndia on using #PostgreSQL vectors to find the best coffee ☕. Big thanks to @clairegiordano for the shout out & everyone for the great energy! Also, yes, caffeine levels were high. 😆 @AzureDBPostgres #PostGIS #VectorSearch
On the big ballroom stage at @PGConfIndia in Bengaluru is @iVarund from the @AzureDBPostgres team giving his talk about “Using Postgres to locate the best coffee near you!” And to teach us about how to use #PostgreSQL with vectors for semantic search, Varun used data about local coffeeshops, a local delivery service called Zomato, a cameo by Dora the Explorer, vector comparisons by @pamelafox … and apparently Varun himself had several (!!) coffees before getting up on stage. All in all a quite good session with a ton of audience involvement.

AI apps need more than transactions—they need databases built for reasoning. At #MSBuild, see how Azure Databases power AI directly in the database layer, simplifying your stack and enabling real-time intelligence. Plus, get a look at building AI apps with #AzureHorizonDB.
