I have found an issue: when reading large CSV files, for example, when a single CSV file in a table is 300M, the peak memory usage of arrow memory pool during single-threaded reading can reach 500M. If the CSV is 2G, the peak memory usage can also increase to 1.7G. It looks like there is no memory leak, but the peak memory usage is very high. -- This is an automated message from the Apache Git Service.
