What Does "Pipeline Sync" Mean in Reth?

Pipeline sync refers to Reth's staged, sequential processing architecture for synchronizing blockchain data. It's not a single operation, but rather a multi-stage pipeline that processes blocks through a series of specialized stages in a specific order.

The Core Concept

Instead of downloading and processing blocks all at once, Reth breaks the sync process into 15 distinct stages that run serially:
