Class Tracker

java.lang.Object
io.fluxcapacitor.javaclient.tracking.Tracker
public class Tracker extends Object
Represents the client-side tracking context during message consumption in Flux Capacitor.

This Tracker is used locally in a Flux client to provide filtering and stateful context when consuming message batches. It is automatically set as a thread-local variable for the duration of batch processing, allowing handlers and other logic to access it via current().

      public boolean canHandle(DeserializingMessage message, String routingKey)
      When the consumer is configured with ignoreSegment=true, segment filtering is performed client-side. This method uses the current MessageBatch to determine whether a given message should be processed by the current tracker, based on:
      • The segment range of the batch
      • The index of the message relative to the current Position
      Parameters:
      message - The message to check
      routingKey - The routing key to base the check on
