  :::python

  Example of Using PyArrow RecordBatchReader with deltalake.write_deltalake

  import pyarrow as pa from deltalake import write_deltalake from chdb import session as chs

  sess = chs.Session()

  Get streaming result in arrow format

  stream_result = sess.send_query("SELECT * FROM numbers(100000)", "Arrow")

  Create RecordBatchReader with custom batch size (default rows_per_batch=1000000)

  batch_reader = stream_result.record_batch(rows_per_batch=10000)

  Use RecordBatchReader with external libraries like Delta Lake

  write_deltalake( table_or_uri="./my_delta_table", data=batch_reader, mode="overwrite" )

  stream_result.close()

  sess.close()
