AWS quietly killed Quantum Ledger Database, and its own migration advice points at Postgres. Here's the append-only, audit-grade ledger we actually build there, what you get for free, and the one thing you have to add back by hand.
Multi-cloud promises resilience but usually delivers doubled cost and complexity for an outage that may never come. A look at the DNS trap, AWS's 300+ SLAs, the October 2025 US-EAST-1 outage, and why multi-region discipline beats a second provider.
Most early-stage cloud stack debates are arguments about the wrong question. The tool doesn't matter nearly as much as the cost of switching, who fixes it at 3am, and whether your second engineer can read it.
Deduping messy real-world data, companies, addresses, people, looks like a solved problem until you do it. Here's an honest comparison of the three techniques that actually matter inside Postgres, when each one wins, and where each one quietly breaks.
After replacing Mondrian's SQL emitter with Calcite, the next obvious target was the data path itself: an Apache Arrow segment cache and ADBC connections to replace JDBC. The first benchmarks said Arrow was 2.6x slower. They were wrong, but not for the reasons I expected. Here's the honest report on where columnar wins, where it ties, and where it actually loses.
Years ago I walked away from Saiku, the commercial open source OLAP tool I'd built and run for the better part of a decade. This year, with a few weeks off and an agentic coding agent at my disposal, I rebuilt it, new UI, modernised dependencies, and a new SQL engine underneath. Here's what happened, and why I'm releasing it again.
