Moving Quicksilver into production

This post details the migration of Quicksilver, a core distributed data store, from Kyoto Tycoon to a new system. It describes the implementation of QSKTBridge for parallel replication and phased rollout, the challenges encountered with replication saturation due to bootstrapping and I/O saturation from aging SSDs, and the performance improvements observed after migrating the FL component to Quicksilver. It also discusses the evolution of replication topology management from static Salt configurations to dynamic DNS-based approaches.
