Python: Calling to_pandas on a table read from Parquet leaks memory

    • Type: Bug

      Description

      Steps to reproduce:

      • Read a parquet file with pyarrow.parquet.read_table and convert the table to a DataFrame with to_pandas
      • Repeat this several times and see an ever increasing memory usage

      This seems to happen only in this combination. Calling gc.collect doesn't help.
