Abstract Value Members

abstract def run(metastore: MetastoreReader, infoDate: LocalDate, options: Map[String, String]): DataFrame

A job has access to the metastore where it can query tables registered in the configuration.
A job has access to the metastore where it can query tables registered in the configuration.
If task fails it should throw a runtime exception.
Do not add information date column to the output dataframe. It will be added automatically. If the information date column exists in the output dataframe, it will be deleted and replaced by the framework.
metastore
The read only version of metastore. You can only query tables using it.
infoDate
The information date of the output of the transformation.
options
Extra options specified in the configuration for the transformation.
returns
The output DataFrame
abstract def validate(metastore: MetastoreReader, infoDate: LocalDate, options: Map[String, String]): Reason

Validates if the transformation can run.
Validates if the transformation can run.
If the transformation can run for the given information date, it should return Reason.Ready.
If requirements are not met the validation routine should do one of teh following: - return Reason.NotReady - this means some input data is missing, but the transformation can run in the future when the requirements are met - return Reason.Skip - this means the running of the transformation should be completely skipped. - throw an exception - this will result in the same behavior as returning Reason.NotReady
metastore

infoDate
The information date of the output of the transformation.
options
Extra options specified in the configuration for the transformation.
returns
Reason as the validation result.
