Functions

break_query_cycles

Detects query cycles by using depth first search over all active query jobs. If a query cycle is found it will break the cycle by finding an edge which uses a query latch and then resuming that waiter. There may be multiple cycles involved in a deadlock, so this searches all active queries for cycles before finally resuming all the waiters at once.

collect_active_query_jobs

Returns a map of currently active query jobs, collected from all queries.
