Package org.apache.calcite.benchmarks

Class FlightRecorderProfiler

  • All Implemented Interfaces:
    org.openjdk.jmh.profile.ExternalProfiler, org.openjdk.jmh.profile.Profiler
    public class FlightRecorderProfiler
extends java.lang.Object
implements org.openjdk.jmh.profile.ExternalProfiler
    Captures Flight Recorder log. Note: Flight Recorder is available in OracleJDK only. Usage of Flight Recorder in production requires a LICENSE FEE, however Flight Recorder is free for use in test systems. It is assumed you would not use Calcite benchmarks for running a production system, thus it is believed to be safe.
