TahoeChangeFileIndex

class TahoeChangeFileIndex extends TahoeFileIndexWithSnapshotDescriptor

A TahoeFileIndex for scanning a sequence of CDC files. Similar to TahoeBatchFileIndex, the equivalent for reading AddFile actions.

Note: Please also consider other CDC-related file indexes like CdcAddFileIndex and TahoeRemoveFileIndex when modifying this file index.

    Returns (i) tuples of partition directories to their respective AddFile actions and (ii) a collection of matched AddFiles. The matched AddFiles are those that meet the criteria set by the partition and data filters. Essentially, this is a collection of all the files associated with the identified partitions.

    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.
