Column Storage for the AI Era
In the past few years, we’ve seen a cambrian explosion of new columnar formats, challenging the hegemony of Parquet: Lance, Fastlanes, Nimble, Vortex, AnyBlox, F3 (File Format for the Future). The thinking is that the context has changed so much that the design of yore (the previous decade) is not going to cut it moving forward. This seemed a bit intriguing to me, especially since the main contribution of Parquet has been to provide a standard for columnar storage. Parquet is not simply a file format. As an open source project hosted by the ASF, it acts as a consensus building machine for the industry. Creating six new formats is not going to help with interroperability. I spent some time to understand a bit better how things actually changed and how Parquet needs to adapt to meet the demands of this new era. In this post I’ll discuss my findings.
outl — local-first markdown outliner & LLM second brain
Open-source bullet-point outliner. Plain markdown on disk (no UUIDs), peer-to-peer tree-CRDT sync that doesn't lose data when devices edit offline — your devices talk straight to each other, end-to-end encrypted, no cloud or third-party server holding your notes — and an MCP server so Claude, Cursor and ChatGPT use your notes as a second brain. A modern Roam, Logseq and Obsidian alternative built in Rust.
