From Database Changes to Real-Time Actions at Scale: Oracle GoldenGate and Java

DB changes can be streamed in real time via Oracle GoldenGate. Java applications can then consume them to validate/act on/route events without polling the DB.

Goal

Listen to real-time transactions in the DB, act on all operations within transactions, and maintain transaction boundaries with near real-time SLAs.

Each invocation behaved as an independent conversation, and the workflow broke on its second step. No exception, no warning. Just a server that had forgotten who you are.

Best of Three Worlds: AI Agents Writing In Rust and Java Beat the C Library

Every app that accepts photo uploads meets HEIC sooner or later. iPhones save in it by default. Neither Java nor Rust can read it out of the box, and the usual answer, libheif, is a C library: native packages in every container image, a C toolchain in the build, and a parser written in C reading files that strangers upload.

I had the problem twice, in a Java product and in a Rust one. So I went the other way: decoders written in the language itself, built and improved by AI coding agents, with me steering. Here is how it went.
