> In [TransactionalIdsGenerator.java|#L94]], prefix contains taskName of the
> particular task which could ultimately contain user code. In some cases,
> user code contains conversion specifiers like %, the string formatting could
> fail.
> For example, in Flink SQL code, user could have a LIKE statement with a %
> wildcard, the % wildcard will end up in the prefix and get mistreated during
> formatting, causing task to fail.
> Think we should move prefix out of the string formatting.
