Today I want to talk about partial decompression in PostGIS and how it has improved the speed of some operations with large geometries, that is the geometries made of hundreds of points or vertices. I don’t think we’ve intentionally focused on performance for the upcoming PostGIS 3.1 but unconsciously I... [Read More]

Snowflake seems like one of the hottest databases of the moment. Sorry, data warehouse. Tomayto, tomahto. Anyway, I wanted to give it a try and see how hard it is to add new SQL functions to it. [Read More]

To continue with the changes in PostGIS 3.1, in this post I’ll cover the performance improvements on many functions that output geometries either as binary or as text. I will talk about several changes which have in common that they kicked off by a single question: “Now what?” [Read More]

I’m not big on creating new things, I would rather work on improving something that’s already in use and has proven its usefulness. So whenever I’m thinking about what I should do next I tend to look for projects or features that are widely used, where the balance between development... [Read More]
