This week we announced a new ADBC driver for Apache DataFusion. DataFusion is Rust-native, but now you can use it from 10+ other languages through the same zero-copy Arrow ADBC interface that connects to 30+ other databases and query engines. Learn more: docs.adbc-drivers.org/drivers/data...

Apache DataFusion Comet 0.16.0 is now available, and I’m pretty excited about this one! Comet now has first-class support for Spark 4.0 and 4.1 with full ANSI support for overflow checks, ANSI casts, try_* variants of some expressions, all accelerated. datafusion.apache.org/blog/output/...

There's a new DataFusion subproject to provide official Java bindings. It's very early, and it's a great time for new contributors to get involved! github.com/apache/dataf...

Much of this write up is true, although it mixes me up with @andrewlamb1111.bsky.social in places. It also neglects to mention the hard work of literally hundreds of people in the community that took my initial donations and transformed them into something amazing today.

Helpful advice. Thanks, Claude.

I've posted my latest recap of the world of databases: www.cs.cmu.edu/~pavlo/blog/... All the hot topics from the last year: • More Postgres action! • MCP for everyone! • MongoDB gets litigious with FerretDB! • File formats! • Market movements! • The richest person in the history of the world!

I've been helping our analytics team integrate our DataFusion-based query engine for Postgres into EDB Postgres Distributed and finally here's an end-to-end demo. You get HA Postgres plus seamless replication and DataFusion-based queries. This query turned out 6x faster than PG.

One month on, and I have zero regrets about quitting Facebook & Instagram. I have replaced the scrolling time with listening to podcasts. I now stay in touch with family overseas via email and photo sharing, and I use Snapchat for sharing photos with immediate family, privately. Works great.

Andy Grove@andygrove.io · 2y ago

I've finally decided to quit using Facebook. My feed is overwhelmed with nonsense content that I am not interested in and cannot seem to block. It is a real shame, though, because it was a good way to stay connected with family. Is there a viable alternative? What are others using instead?
