ACERCA DE ESTE EPISODIO
The ClickHouse® project is a rising star in observability and analytics, challenging performance conventions with its breakneck speed. This open source OLAP column store, originally developed at Yandex to power their web analytics platform at massive scale, has quickly evolved into one of the hottest open source observability data stores around. Its published performance benchmarks have been the topic of conversation, outperforming many legacy databases and setting a new bar for fast queries over large volumes of data.
Our guest for this episode is Robert Hodges, CEO of Altinity — the second largest contributor to the ClickHouse project. With over 30 years of experience in databases, Robert brings deep insights into how ClickHouse is challenging legacy databases at scale. We’ll also explore Altinity’s just-launched groundbreaking open source project—Project Antalya—which extends ClickHouse with Apache Iceberg shared storage, unlocking dramatic improvements in both performance and cost efficiency. Think 90% reductions in storage costs and 10 to 100x faster queries, all without requiring any changes to your existing applications.
