  1. 有很多地址可以调,比如直接内存配比、内存管理器glibc参数、taskmanager、jobmanager内存大小、状态配置、等等 详见:https://nightlies.apache.org/flink/flink-docs-release-1.13/docs/deployment/config/

    比如:

    table.exec.source.cdc-events-duplicate = truestate.backend = rocksdbstate.backend.incremental = truestate.checkpoints.dir = hdfs:///user/flink/{notebook}execution.checkpointing.unaligned = trueexecution.checkpointing.interval = 300000execution.checkpointing.min-pause = 60000execution.checkpointing.max-concurrent-checkpoints = 1execution.checkpointing.tolerable-failed-checkpoints = 1execution.checkpointing.externalized-checkpoint-retention = RETAIN_ON_CANCELLATIONtaskmanager.numberOfTaskSlots = 2jobmanager.memory.process.size = 2048mtaskmanager.memory.process.size = 4096mtaskmanager.memory.managed.fraction = 0.6

  2. 需要登录实时计算管理控制台,然后在Flink全托管页签,单击目标工作空间操作列下的控制台,在自动调优页签,单击配置,可以根据自己需求配置。

  3. Flink的容器调优可以在flink-conf.yaml文件中进行

  4. Flink全托管支持自动调优和定时调优两种调优模式,详情可参考配置自动调优
