MariaDB has announced Enterprise Platform 2026 with a clear pitch to developers, data teams and DBAs: unify the transactional, analytical and vector engines in one high-performance platform, add built-in RAG and AI agents, and run it in a serverless cloud to handle the elastic, unpredictable demand of agentic applications. The promise: fewer moving parts, lower […]| System Administration

The idealized model of a transactional data storage system is one of a sequential, serializable system, where clients can submit transactions and the system ensures the outcomes are as if those transactions were executed against a single copy of that data. In practice, performance limitations of this model have historically pushed systems to explore a wide set of alternative, weakly consistent models.| William Schultz

This Berkeley systems group paper opens with the thesis that LLM agents will soon dominate data system workloads. These agents, acting on behalf of users, do not query like human analysts or even like the applications written by them. Instead, the LLM agents bombard databases with a storm of exploratory requests: schema inspections, partial aggregates, speculative joins, rollback-heavy what-if updates. The authors calls this behavior agentic speculation.| Metadata
This paper from SIGMOD 2016 proposes a transaction healing approach to improve the scalability of Optimistic Concurrency Control (OCC) in main-memory OLTP systems running on multicore architectures. Instead of discarding the entire execution when validation fails, the system repairs only the inconsistent operations to improve throughput in high-contention scenarios.| Metadata

There are books & many articles online, like this one arguing for using Postgres for everything. I thought I’d take a look at one use case - using Postgres instead of Redis for caching. I work with APIs quite a bit, so I’d build a super simple HTTP server that responds with data from that cache. I’d start from Redis as this is something I frequently encounter at work, switch it out to Postgres using unlogged tables and see if there’s a difference.| Dizzy zone
