CdcAddFileIndex

class CdcAddFileIndex extends TahoeBatchFileIndex

A TahoeFileIndex for scanning a sequence of added files as CDC. Similar to TahoeBatchFileIndex, with a bit of special handling to attach the log version and CDC type on a per-file basis.

  1. new CdcAddFileIndex(spark: SparkSession, filesByVersion: Seq[CDCDataSpec[AddFile]], deltaLog: DeltaLog, path: Path, snapshot: SnapshotDescriptor, rowIndexFilters: Option[Map[String, RowIndexFilterType]] = None)

    spark

    The Spark session.

    filesByVersion

    Grouped FileActions, one per table version.

    deltaLog

    The delta log instance.

    path

    The table's data path.

    snapshot

    The snapshot where we read CDC from.

    rowIndexFilters

    Map from URI-encoded file path to a row index filter type.

    Returns all matching/valid files by the given partitionFilters and dataFilters. Implementations may avoid evaluating data filters when doing so would be expensive, but *must* evaluate the partition filters; wrong results will be produced if AddFile entries which don't match the partition filters are returned.
