  14. def listFiles(partitionFilters: Seq[Expression], dataFilters: Seq[Expression]): Seq[PartitionDirectory]

    Returns all valid files grouped into partitions when the data is partitioned.

    Returns all valid files grouped into partitions when the data is partitioned. If the data is unpartitioned, this will return a single partition with no partition values.

    partitionFilters

    The filters used to prune which partitions are returned. These filters must only refer to partition columns and this method will only return files where these predicates are guaranteed to evaluate to true. Thus, these filters will not need to be evaluated again on the returned data.

    dataFilters

    Filters that can be applied on non-partitioned columns. The implementation does not need to guarantee these filters are applied, i.e. the execution engine will ensure these filters are still applied on the returned files.

  15. def metadataOpsTimeNs: Option[Long]

    Returns an optional metadata operation time, in nanoseconds, for listing files.

    Returns an optional metadata operation time, in nanoseconds, for listing files.

    We do file listing in query optimization (in order to get the proper statistics) and we want to account for file listing time in physical execution (as metrics). To do that, we save the file listing time in some implementations and physical execution calls it in this method to update the metrics.
