### Is your feature request related to a problem or challenge? The encoding of parquet requires a [non-trivial amount of memory buffering](https://docs.rs/parquet/latest/parquet/arrow/arrow_writer/struct.ArrowWriter.html#memory-limiting). During the execution of datafusion physical plans, parquet may be encoded using [ParquetSink](https://github.com/apache/datafusion/blob/782df390078b1aee157d999898424c23530c3eca/datafusion/core/src/datasource/file_format/parquet.rs#L591) (e.g. `COPY TO` queries which output parquet). Currently we do not track ParquetSink's memory usage in the task context's memory pool. ### Describe the solution you'd like Start tracking the memory used during parquet encoding. ### Describe alternatives you've considered _No response_ ### Additional context Recently, we [extended several parquet](https://github.com/apache/arrow-rs/pull/5967) interfaces to provide better estimates of the `memory_usage` during encoding. These memory usage estimates should be used to determine the appropriate memory reservations. -- This is an automated message from the Apache Git Service.
