If a query is executed from the MySQL command line, then
KILLed it while it is running will the query and its partial results* be in the query cache and usable to subsequent runs of the identical query?
For simplicity's sake, let's say this is a plain old
SELECT with no subqueries.
The list of exclusions on this page covers cases in which queries will not be cached such as the queried table changing between executions, and certain operations that are by nature not identical, but I do not see interrupted or killed queries listed anywhere. It must not be that a killed query is treated the same as one that ran to completion, but if it met all of the other criteria for caching it would already be cached* before it got killed, so I'm wondering what happens next.
*I'm making several assumptions here.
