Stream tricks that you don't wanna miss ! by Aicha Laafia

A conference talk transcript covering Java Stream Gatherers introduced in JDK 25. The speaker explains the four components of a custom gatherer (initializer, integrator, combiner, finisher) and demonstrates five built-in gatherers: windowFixed, windowSliding, scan, fold, and mapConcurrent. Live demos using Formula 1 race data show how gatherers replace verbose custom collectors and for-loop workarounds for batching, sliding windows, and stateful accumulation across a stream pipeline.
