使用 JFR（JAVA FlightRecorder）性能调优批量导入执行流程

[baisui1981]

在执行MySQL->MySQL 的pipeline管道同步流程中发现日志中，某几次打印流量同步的数据量为0，如下：

猜测执行过程有哪个执行流程block住了，使用 JFR（JAVA FlightRecorder）进行性能分析

java -XX:+UnlockCommercialFeatures -XX:+FlightRecorder -XX:+UnlockDiagnosticVMOptions -XX:+DebugNonSafepoints -XX:FlightRecorderOptions=defaultrecording=true,dumponexit=true,dumponexitpath=/tmp/instancedetail.jfr -Ddata.dir=/tmp/release/tis-uber/data -Denv_props=false -Dlog.dir=/tmp/release/tis-uber/logs -Druntime=daily -Dlogback.configurationFile=logback-datax.xml -DexecTimeStamp=1713576914309 -DnotFetchFromCenterRepository=true -classpath /tmp/release/tis-uber/tis-assemble/lib/*:/tmp/release/tis-uber/data/libs/plugins/tis-datax-local-executor/WEB-INF/lib/*:/tmp/release/tis-uber/tis-assemble/conf:/tmp/release/tis-uber/web-start/lib/* com.qlangtech.tis.datax.DataxExecutor 3 instancedetail_0.json/order2/instancedetail mysql_mysql 127.0.0.1:56432 local -1 ap 1 1713576914309

添加JVM 参数为：
