opt: explicit planning of sort algorithms #38032

Open justinj opened 5 years ago

justinj commented 5 years ago

Today, the optimizer just has a single sort, which doesn't distinguish between a global sort, top-k, or segmented sort. We just set up the situations where they can be used and rely on distsql to plan the correct sort algorithm. It would be better if all this decision making was explicitly centralized in the optimizer.

Jira issue: CRDB-5655
