All Implemented Interfaces:
io.perl.logger.PerformanceLogger, io.perl.logger.Print, io.perl.logger.ReportLatency, CountReaders, CountRW, CountWriters, Logger, ReadRequestsLogger, RWLogger, RWPrint, SetRW, WriteRequestsLogger
Direct Known Subclasses:

public abstract class AbstractRWLogger extends io.perl.logger.impl.ResultsLogger implements RWLogger, SetRW
Base implementation of RWLogger providing shared read/write request accounting, periodic aggregation, and printing helpers. Subclasses implement concrete outputs (System out, CSV, Prometheus, gRPC) by overriding the print methods while reusing the counters, percentiles, and CLI configuration handling provided here.
