In group by execution (reacheable from both single and multi-stage), `DictionaryBasedGroupKeyGenerator`'s thread local maps do not clear / trim until next construction. We could trim after `GroupByCombineOperator` use them [here](https://github.com/apache/pinot/blob/45389974f6fad5a5f35b074d06063673112e8dc2/pinot-core/src/main/java/org/apache/pinot/core/operator/combine/GroupByCombineOperator.java#L146). [See here](https://github.com/apache/pinot/blob/45389974f6fad5a5f35b074d06063673112e8dc2/pinot-core/src/main/java/org/apache/pinot/core/query/aggregation/groupby/DictionaryBasedGroupKeyGenerator.java#L150C2-L150C75) -- This is an automated message from the Apache Git Service.
