> SMB joins are used wherever the tables are sorted and bucketed. It's a map-side join.
The join boils down to just merging the already sorted tables, allowing this operation to
be faster than an ordinary map-join.
> The task is to research and support the conversion from regular SMB join to SMB map join
for Spark execution engine.
