Class BlobTransferGlobalTrafficShapingHandlerHolder

java.lang.Object
com.linkedin.davinci.blobtransfer.BlobTransferGlobalTrafficShapingHandlerHolder
public class BlobTransferGlobalTrafficShapingHandlerHolder extends Object
Singleton holder for the GlobalChannelTrafficShapingHandler. This class provides a thread-safe way to access a single instance of the global traffic shaping handler that can be shared across all network channels of blob transfer in both server and client side to enforce global rate limits. Because this is a JVM-wide singleton shared by both server and DaVinci client components, no explicit LogContext is set on the traffic-shaper thread. The thread may inherit context from its creating thread when log4j2.isThreadContextMapInheritable=true.
