  11. def extract(lastRunDateTime: LocalDateTime, currentRunDateTime: LocalDateTime): Map[String, DataFrame]

    Reads data from a file system and produces a Map[DatasetConf, DataFrame].

    Reads data from a file system and produces a Map[DatasetConf, DataFrame]. This method should avoid transformation and joins but can implement filters in order to make the ETL more efficient.

    returns

    all the data needed to pass to the transform method and produce the desired output.

    replaceWhere is used in for OverWriteStaticPartition load.

    replaceWhere is used in for OverWriteStaticPartition load. It avoids to compute dataframe to infer which partitions to replace. Most of the time, these partitions can be inferred statically. Always prefer that to dynamically overwrite partitions.
