Instance Constructors

  1. new DeltaIdentityColumnStatsTracker(hadoopConf: Configuration, path: Path, dataCols: Seq[Attribute], statsColExpr: Expression, identityColumnInfo: Seq[(String, Boolean)])

    hadoopConf

    The Hadoop configuration object to use on an executor.

    path

    Root Reservoir path

    dataCols

    Resolved data (i.e. non-partitionBy) columns of the dataframe to be written.
