How does this change output
{quote}
It does not change output, but it changes output directory structure. It used
to be flat, now it adds subdirectories for every table:
If we convert WALs for tables T1, T2, T3 the tool will create separate
directories for each table:
T1/
T2/
T3/
> Backup: further optimizations
