    https://github.com/apache/spark/pull/16281
  
    For this issue, it was initially PARQUET-363, but all maintenance fix (with 
new features) are welcome.
    
    For me, the followings?
    
    - PARQUET-99: Large rows cause unnecessary OOM exceptions
    - PARQUET-353: Compressors not getting recycled while writing parquet 
files, causing memory leak
    - PARQUET-363: Cannot construct empty MessageType for 
ReadContext.requestedSchema
    - PARQUET-511: Integer overflow on counting values in column
    - PARQUET-569: ParquetMetadataConverter offset filter is broken
    - PARQUET-571: Fix potential leak in ParquetFileReader.close()
    - PARQUET-623: DeltaByteArrayReader has incorrect skip behaviour
    - PARQUET-645: DictionaryFilter incorrectly handles null
    
    @gatorsmile . Do you have more?
