Concept of the episode: Peaka

Another Trino Community Broadcast episode means another cool piece of technology that uses Trino for us to show off to the community. This time it’s Peaka, a no-code approach to date warehousing that makes it easier than ever to set up your data stack without needing a ton of complex engineering.

In their own words, Peaka is a platform that merges disparate data sources into a single data layer, letting you join and blend them, query them using SQL or natural language, and expose your data to outside users through APIs. Sounds a bit like Trino, right? That’s because underneath the hood, Trino is a key part of how they’re making it happen. In this episode, we talk to the team at Peaka about where they got started, how they’re making it easier than ever to leverage the federation that Trino is capable of, and the work they’ve done on top to integrate their platform with every SaaS data source under the sun.

Demo of the episode: Using Peaka!

If you want to see what the platform is like, then look no further. We’ll be exploring:

• Connecting to data sources
• Filtering and combining data
• Editing and running queries, including their visual query editor
• Natural language queries
• Visualizing data

PR of the episode: #18719: Filesystem caching with Alluxio

Perhaps it’s a little easier to link to the issue for tracking the rollout, but however you want to present it, caching in Trino is renewed! Caching is a huge performance win for a wide variety of use cases, allowing the engine to run faster, better, and pump out query results at an unparalleled pace. This is going to lead to performance improvements for Trino queries using the supported object storage connectors, and you’ll hear more from us about it once it’s officially launched. The best part is that there’s even more coming down the line as support for it is expanded.
