Build bitmap compressed sets of row indices for each file in target using ROW_INDEX_COL.
Build bitmap compressed sets of row indices for each file in target using ROW_INDEX_COL. Write those sets out to temporary files and collect the file names, together with some encoded metadata about the contents.
