Object Storage + WAL: Lakebase Postgres for the agentic era

This post details the integration of Postgres Write-Ahead Logging (WAL) with object storage to enable a unified OLTP and OLAP data plane, specifically for the 'agentic era'. It describes how WAL files are streamed to object storage, allowing for near real-time querying of transactional data alongside analytical data in the Lakehouse. This addresses the challenge of providing low-latency access to transactional data for AI agents and other applications that require up-to-date information without the overhead of traditional replication or ETL.
