Description

We've had some users recently complain that the default MAX_SUBST hardcode of 20 isn't sufficient for their substitution needs and they wished it were configurable rather than having to roll about with workarounds such as using temporary smaller substitutes and then building the fuller one after it. We should consider raising the default hardcode, or provide a way to make it configurable instead.

Related: HIVE-2021 changed something similar for their HiveConf classes.
