Constructor Detail

InsertPlan

public InsertPlan(Operator.OperatorType operatorType)

Method Detail

getDevicePath

public org.apache.iotdb.commons.path.PartialPath getDevicePath()

if use id table, this filed is id form of device path
if not, this filed is device path
used in flush time manager, last cache, tsfile processor

getMeasurements

public java.lang.String[] getMeasurements()

markFailedMeasurementInsertion

public void markFailedMeasurementInsertion(int index,
                                           java.lang.Exception e)

This method is overrided in InsertRowPlan and InsertTabletPlan. After marking failed measurements, the failed values or columns would be null as well. We'd better use "measurements[index] == null" to determine if the measurement failed.

Parameters:

index - failed measurement index

getPlanFromFailed

public InsertPlan getPlanFromFailed()

Reconstruct this plan with the failed measurements.

Returns:

the plan itself, with measurements replaced with the previously failed ones.

recoverFromFailure

public void recoverFromFailure()

Reset measurements from failed measurements (if any), as if no failure had ever happened.

checkIntegrity

public void checkIntegrity()
                    throws QueryProcessException

Description copied from class: PhysicalPlan

Check the integrity of the plan in case that the plan is generated by a careless user through Session API.

Overrides:

checkIntegrity in class PhysicalPlan

Throws:

QueryProcessException - when the check fails

getDeviceID

public IDeviceID getDeviceID()

device id reference, for reuse device id in both id table and memtable
used in memtable

setDeviceID

public void setDeviceID(IDeviceID deviceID)
