  6. def compact(datasetConf: DatasetConf, partitionFilter: Option[String] = None)(implicit spark: SparkSession, conf: Configuration): Unit

    Compact the data by coalescing small files into larger ones.

    Compact the data by coalescing small files into larger ones.

    datasetConf

    Dataset to compact

    partitionFilter

    Optional partition predicate to only compact a subset of data

    spark

    Spark session

    conf

    Configuration

    Examples:

    1. Compact the whole dataset.

      compact(ds)
      2. ,

    2. Compact a specific partition. Useful for compaction jobs running everyday on the same dataset.

      compact(ds, Some("date='2020-01-01'"))

  18. def vacuum(datasetConf: DatasetConf, numberOfVersions: Int)(implicit spark: SparkSession, conf: Configuration): Unit

    Vacuum based on the number of versions we wants keep.

    Vacuum based on the number of versions we wants keep. Notes : - If there is versions younger than 2 weeks then these versions will be kept and the retention period will be set to 336 hours (2 weeks) - If there is less versions than numberOfVersions param then vacuum will not be executed

    datasetConf

    dataset to vacuum

    numberOfVersions

    number of versions to kept

    spark

    spark session

    conf
