PreparedDeltaFileIndex

case class PreparedDeltaFileIndex(spark: SparkSession, deltaLog: DeltaLog, path: Path, preparedScan: DeltaScan, versionScanned: Option[Long]) extends TahoeFileIndexWithSnapshotDescriptor with DeltaLogging with Product with Serializable

A TahoeFileIndex that uses a prepared scan to return the list of relevant files. This is injected into a query right before query planning by PrepareDeltaScan so that CBO and metering can accurately understand how much data will be read.

versionScanned

The version of the table that is being scanned, if a specific version has specifically been requested, e.g. by time travel.
