* We resolve this by getting all the actions_id that we want to release claim from in a separate query, and then releasing the claim on each of them. This way, our lock is acquired on the action_id index instead of the claim_id index. Note that the lock on claim_id will still be acquired, but it will only when we actually make the update, rather than when we select the actions.
