Document effect on distribution of left record set for half-keyed join

Environment

Thor

Description

The documentation indicates grouping is preserved on the left record set of a half-keyed join but is silent on the impact of the distribution of the left record set.

The documentation does specify a behavior for LOCAL, indicating that only the local index is accessed.

Conclusion

None

Whether it's a half-keyed join or a full-keyed join, LOCAL or global, the LHS order (and hence distribution) is preserved by default.
If ,UNORDERED is used, the LHS order is not preserved, although the distribution still is.
