> Account the survivor buffer of the late-materialization Parquet reader
> (SPARK-59620) to the task's execution memory through a MemoryConsumer. A
> denied reservation gives splicing up, as passing
> spark.sql.parquet.storageFilterPushdown.maxSplicedRowGroupBytes does, and a
> spill frees the survivor key values not yet emitted, which the reader then
> reads again.
