buildRowIndexSetsForFilesMatchingCondition¶

buildRowIndexSetsForFilesMatchingCondition(
  sparkSession: SparkSession,
  txn: OptimisticTransaction,
  tableHasDVs: Boolean,
  targetDf: DataFrame,
  candidateFiles: Seq[AddFile],
  condition: Expression): Seq[DeletionVectorResult]

buildRowIndexSetsForFilesMatchingCondition adds the following columns to the input targetDf DataFrame:

Column Name	Column
`filePath`	`_metadata.file_path`
`rowIndexCol`	__delta_internal_row_index

buildRowIndexSetsForFilesMatchingCondition filters out the rows based on the given condition expression.
