/// Encodes [`RecordBatch`] to parquet
///
/// Writes Arrow `RecordBatch`es to a Parquet writer. Multiple [`RecordBatch`] will be encoded
/// to the same row group, up to `max_row_group_size` rows. Any remaining rows will be
/// flushed on close, leading the final row group in the output file to potentially
/// contain fewer than `max_row_group_size` rows
///
/// # Example: Writing `RecordBatch`es
/// ```
/// # use std::sync::Arc;
/// # use bytes::Bytes;
/// # use arrow_array::{ArrayRef, Int64Array};
/// # use arrow_array::RecordBatch;
/// # use parquet::arrow::arrow_writer::ArrowWriter;
/// # use parquet::arrow::arrow_reader::ParquetRecordBatchReader;
/// let col = Arc::new(Int64Array::from_iter_values([1, 2, 3])) as ArrayRef;
/// let to_write = RecordBatch::try_from_iter([("col", col)]).unwrap();
///
/// let mut buffer = Vec::new();
/// let mut writer = ArrowWriter::try_new(&mut buffer, to_write.schema(), None).unwrap();
/// writer.write(&to_write).unwrap();
/// writer.close().unwrap();
///
/// let mut reader = ParquetRecordBatchReader::try_new(Bytes::from(buffer), 1024).unwrap();
/// let read = reader.next().unwrap().unwrap();
///
/// assert_eq!(to_write, read);
/// ```
///
/// # Memory Usage and Limiting
///
/// The nature of Parquet requires buffering of an entire row group before it can
/// be flushed to the underlying writer. Data is mostly buffered in its encoded
/// form, reducing memory usage. However, some data such as dictionary keys,
/// large strings or very nested data may still result in non-trivial memory
/// usage.
///
/// See Also:
/// * [`ArrowWriter::memory_size`]: the current memory usage of the writer.
/// * [`ArrowWriter::in_progress_size`]: Estimated size of the buffered row group,
///
/// Call [`Self::flush`] to trigger an early flush of a row group based on a
/// memory threshold and/or global memory pressure. However,  smaller row groups
/// result in higher metadata overheads, and thus may worsen compression ratios
/// and query performance.
///
/// ```no_run
/// # use std::io::Write;
/// # use arrow_array::RecordBatch;
/// # use parquet::arrow::ArrowWriter;
/// # let mut writer: ArrowWriter<Vec<u8>> = todo!();
/// # let batch: RecordBatch = todo!();
/// writer.write(&batch).unwrap();
/// // Trigger an early flush if anticipated size exceeds 1_000_000
/// if writer.in_progress_size() > 1_000_000 {
///     writer.flush().unwrap();
/// }
/// ```
///
/// ## Type Support
///
/// The writer supports writing all Arrow [`DataType`]s that have a direct mapping to
/// Parquet types including  [`StructArray`] and [`ListArray`].
///
/// The following are not supported:
///
/// * [`IntervalMonthDayNanoArray`]: Parquet does not [support nanosecond intervals].
///
/// [`DataType`]: https://docs.rs/arrow/latest/arrow/datatypes/enum.DataType.html
/// [`StructArray`]: https://docs.rs/arrow/latest/arrow/array/struct.StructArray.html
/// [`ListArray`]: https://docs.rs/arrow/latest/arrow/array/type.ListArray.html
/// [`IntervalMonthDayNanoArray`]: https://docs.rs/arrow/latest/arrow/array/type.IntervalMonthDayNanoArray.html
/// [support nanosecond intervals]: https://github.com/apache/parquet-format/blob/master/LogicalTypes.md#interval
///
/// ## Type Compatibility
/// The writer can write Arrow [`RecordBatch`]s that are logically equivalent. This means that for
/// a  given column, the writer can accept multiple Arrow [`DataType`]s that contain the same
/// value type.
///
/// For example, the following [`DataType`]s are all logically equivalent and can be written
/// to the same column:
/// * String, LargeString, StringView
/// * Binary, LargeBinary, BinaryView
///
/// The writer can will also accept both native and dictionary encoded arrays if the dictionaries
/// contain compatible values.
/// ```
