Parquet checks Block size after writing records to decide when it shall flush. This is relatively expensive, so it estimates the next check based on record size, record count etc. For small records less than 1byte after compression, the average record size is 0 after integer division. This caused overflow when calculating the next record count for block size check. It results in block size being checked for every record and slows down write. Fix the zero record size issue with float type record size. Make sure you have checked _all_ steps below. -- This is an automated message from the Apache Git Service.
