DFLib just got a parsable expression grammar. Those expressions can be thought of as parts of SQL for the purpose of column transformation, filtering and (soon) DataFrame sorting

Happy to announce M3, a major new milestone of DFLib 2.0.0. The highlight of this release is a new "expression language" : df.cols("a").merge("int(a) * 35.") // instea...

Particularly exited to start using switch/case/when and other J21 goodies in the Bootique core.
Bootique 3.0 release candidate was just posted. It finalizes Jakarta port, introducing "jakarta.inject" support and also CLI integration improvements. 3.0 GA is now very close. We also kicked off 4.0 work based on the latest Jakarta and Java 21+.

The first milestone of DFLib (Java DataFrame) v2 is out. Lots of improvements, e.g: .* 8x reduction of memory footprint of bool columns.* Major new capabilities in "window" expressions .* Shortened aggregation syntax in "group" expressions .* Heatmap charts

On the heels of DFLib GA, 1.1.0 is released with: .* web / URL connectors for binary data .* primitive float columns (50% memory savings for cases like #1BRC).* chart item styling (incl. dynamic item sizes - essentially another visual dimension).

Glad to announce the 1.1.0 release of DFLib. DFLib is an open source pure Java DataFrame library. It is great for writing data transformations, ETL, "notebook" data analysis, visualizing ...

Don't post here that much anymore, but this is exciting. DFLib 1.0 reaches GA 🎉💪 Don't let the #bigdata world intimidate you, now you can have a #DataFrame in any #Java app to do fun stuff with data (transformations, joins, ETL, charts, etc.).

The experiment is going well. Today decided to do domain based verification, and voila, I am
Experimenting with B*sky. Looks quiet nice. No ads, very few bots, custom feeds and starter packs are cool. Also, now there are 20mln people there so nothing like my Mas*don ghosttown. If any of the Twitter friends are there, let's connect! My handle is in the profile.

Woah, @liquibase is calling home since v4.30.0! There's a way to disable it, but you need to know about it. Totally not cool. We are upgrading LB in Bootique 3.0-M5, and will disable analytics for our users.
liquibase.com
he latest release of Liquibase 4.30.0 now comes with the ability to automatically send anonymous usage analytics when you run commands.

I find myself often using Series object from DFLib instead of a Java List. It has so many advantages:. * Immutable at the API level.* Content search.* Direct transform API - no need for streams in many cases.* Slice and dice, e.g. "head(-1)".* Conforms to Java Iterable.
