| <div class="block">Pass collations through can have three cases: |
| 1. If sort keys are equal to either left join keys, or right join keys, |
| collations can be pushed to both join sides with correct mappings. |
| For example, for the query |
| select * from foo join bar on foo.a=bar.b order by foo.a desc |
| after traits pass through it will be equivalent to |
| select * from |
| (select * from foo order by foo.a desc) |
| join |
| (select * from bar order by bar.b desc) |
| |
| 2. If sort keys are sub-set of either left join keys, or right join keys, |
| collations have to be extended to cover all joins keys before passing through, |
| because merge join requires all join keys are sorted. |
| For example, for the query |
| select * from foo join bar |
| on foo.a=bar.b and foo.c=bar.d |
| order by foo.a desc |
| after traits pass through it will be equivalent to |
| select * from |
| (select * from foo order by foo.a desc, foo.c) |
| join |
| (select * from bar order by bar.b desc, bar.d) |
| |
| 3. If sort keys are super-set of either left join keys, or right join keys, |
| but not both, collations can be completely passed to the join key whose join |
| keys match the prefix of collations. Meanwhile, partial mapped collations can |
| be passed to another join side to make sure join keys are sorted. |
| For example, for the query |
| select * from foo join bar |
| on foo.a=bar.b and foo.c=bar.d |
| order by foo.a desc, foo.c desc, foo.e |
| after traits pass through it will be equivalent to |
| select * from |

| join |
