A great summary of the database news in 2025

PostgreSQL is the state of the art database with wide range support of features.

If 2023 was the year every DBMS added a vector index, then 2025 was the year that every DBMS added support for Anthropic's Model Context Protocol (MCP)

New file formats emerged. Why not using Parquet?

The main problem with Parquet is not inherent in the format itself. The specification can and has evolved. Nobody expected organizations to rewrite petabytes of legacy files to update them to the latest Parquet version. The problem is that there are so many implementations of reader/writer libraries in different languages, each supporting a distinct subset of the specification. Our analysis of Parquet files in the wild found that 94% of them use only v1 features from 2013, even though their creation timestamps are after 2020.
