> The problem with CREATE INDEX is that it calls a CREATE TABLE operation
> inside the same CREATE INDEX transaction. During listener calls, there are
> some listeners that should run in an out-of-transaction context, for
> instance, Sentry blocks the HMS operation until the DB log notification is
> processed, but if the transaction has not finished, then the
> out-of-transaction listener will block forever (or until a read-time out
> happens).
> A fix would be to add a parameter to the out-of-transaction listener that
> alerts the listener if HMS is in an active transaction. If so, then is up to
> the listener plugin to return immediately and avoid blocking the HMS
> operation.
