> During testing of Z-ordering in test environment i've discovered following issues:
>  # Queries failing for tables w/ enabled Clustering w/ Z-ordering Layout and data-skipping enabled, being unable to read `_SUCCESS` file (automatically created by Spark)
>  # Some of the translations of the original query predicates into Z-index table predicates are translated incorrectly (`!=`, `not like`, etc)
>  # Join merging indexes across commits incorrectly always checks for null first column (instead of Nth column) when picking the result of the merge
