How Bitsets Supercharged Our Backend: Faster String Overlap Checks at Scale

Introduction Ever wondered why your backend slows to a crawl when comparing massive sets of strings? Here’s how we turned a bottleneck into a lightning-fast operation using bitsets. Efficiently checking for overlaps between large sets of strings is a common challenge in high-throughput backend services. Traditional approaches — such as nested loops or hash-based comparisons — can quickly become…
