Method Details

getPipeName

public String getPipeName()

This should be called after executeFromValidateTask(org.apache.iotdb.confignode.procedure.env.ConfigNodeProcedureEnv) and executeFromCalculateInfoForTask(org.apache.iotdb.confignode.procedure.env.ConfigNodeProcedureEnv).

constructPlan

public CreatePipePlanV2 constructPlan()

This should be called after executeFromValidateTask(org.apache.iotdb.confignode.procedure.env.ConfigNodeProcedureEnv) and executeFromCalculateInfoForTask(org.apache.iotdb.confignode.procedure.env.ConfigNodeProcedureEnv).

getOperation

protected PipeTaskOperation getOperation()

Specified by:

getOperation in class AbstractOperatePipeProcedureV2

executeFromValidateTask

public boolean executeFromValidateTask(ConfigNodeProcedureEnv env)
                                throws PipeException

Check the PipePlugin configuration in Pipe. If there is an error, throw PipeException. If there is a Pipe with the same name and there is no IfNotExists condition in createPipeRequest, throw PipeException. If there is an IfNotExists condition, return false. If there is no Pipe with the same name, return true.

Specified by:
