> `ObjectAggregationIterator` shows a directional info message to increase `spark.sql.objectHashAggregate.sortBased.fallbackThreshold`
when the size of the in-memory hash map grows too large and it falls back to sort-based aggregation.
> However, we don't know how much we need to increase. This issue add the size of the current
in-memory hash map size to the log message.
