Thanks for reporting this — it sounds like a metadata parsing issue rather
than a query/runtime problem.
To help narrow it down, could you share:
1. Pinot version(s) affected
2. Whether this occurs only for STRING columns (min/max values),
and roughly how large those values are
3. A snippet of the stack trace showing where the regex parsing
happens (class/method), or the specific metadata property being read
4. Whether this happens during segment load/startup vs query-time
metadata access
If this is caused by regex backtracking on very large metadata values, a
possible mitigation might be limiting or truncating stored min/max values, or
switching to a non-regex parsing approach for properties. Happy to help further
if more details are available.
