字段详细资料

requestType

protected final DataNodeRequestType requestType

requestId

protected final int requestId

targetDataNode

protected final org.apache.iotdb.common.rpc.thrift.TDataNodeLocation targetDataNode

dataNodeLocationMap

protected final java.util.Map<java.lang.Integer,org.apache.iotdb.common.rpc.thrift.TDataNodeLocation> dataNodeLocationMap

Map key: The indices of asynchronous RPC requests

Map value: The target DataNodes of corresponding indices

All kinds of AsyncHandler will remove its targetDataNode from the dataNodeLocationMap only if its corresponding RPC request success

responseMap

protected final java.util.Map<java.lang.Integer,T> responseMap

Map key: The indices(targetDataNode's ID) of asynchronous RPC requests

Map value: The response of corresponding indices

All kinds of AsyncHandler will add response to the responseMap after its corresponding RPC request finished

countDownLatch

protected final java.util.concurrent.CountDownLatch countDownLatch

formattedTargetLocation

protected final java.lang.String formattedTargetLocation
