> Inside Utilities::handleDirectInsertTableFinalPath, the cleanDirectInsertDirectories
method is called sequentially for each element of the directInsertDirectories list, which
might have a large number of elements depending on how many partitions were written. This
current sequential execution could be improved by parallelising the clean up process.
