configure

public void configure(io.cdap.delta.api.Configurer configurer)

Specified by:

configure in interface io.cdap.delta.api.DeltaTarget

createConsumer

public io.cdap.delta.api.EventConsumer createConsumer(io.cdap.delta.api.DeltaTargetContext context)

Specified by:

createConsumer in interface io.cdap.delta.api.DeltaTarget

createTableAssessor

public io.cdap.delta.api.assessment.TableAssessor<io.cdap.delta.api.assessment.StandardizedTableDetail> createTableAssessor(io.cdap.delta.api.Configurer configurer)

failAfter

public static io.cdap.delta.proto.Plugin failAfter(long sequenceNumThreshold,
                                                   File proceedFile)

Get the plugin configuration for a mock target that should fail after it sees an event with a sequence number greater than the given threshold. The target will stop throwing exceptions after the given file exists.

Parameters:

sequenceNumThreshold - throw an exception if the sequence number is greater than this value

proceedFile - stop throwing exceptions when the file exists

Returns:

plugin configuration for the mock source

failImmediately

public static io.cdap.delta.proto.Plugin failImmediately(long sequenceNumThreshold)

Get the plugin configuration for a mock target that should cause the pipeline to fail immediately without retries when it sees an event with a sequence number greater than the given threshold.

Parameters:

sequenceNumThreshold - immediately fail the pipeline if the sequence number is greater than this value

Returns:

plugin configuration for the mock source
