You can use the following functions:

  * garrow_record_batch_import()
    https://arrow.apache.org/docs/c_glib/arrow-glib/record-batch.html#garrow-record-batch-import
  * garrow_record_batch_export()
    https://arrow.apache.org/docs/c_glib/arrow-glib/record-batch.html#garrow-record-batch-export
  * garrow_record_batch_reader_import()
    https://arrow.apache.org/docs/c_glib/arrow-glib/reader-classes.html#garrow-record-batch-reader-import
  * garrow_record_batch_reader_export()
    https://arrow.apache.org/docs/c_glib/arrow-glib/reader-classes.html#garrow-record-batch-reader-export
  * garrow_schema_import()
    https://arrow.apache.org/docs/c_glib/arrow-glib/GArrowSchema.html#garrow-schema-import
  * garrow_schema_export()
    https://arrow.apache.org/docs/c_glib/arrow-glib/GArrowSchema.html#garrow-schema-export

The following functions may be needed:

  * garrow_array_import()
    https://arrow.apache.org/docs/c_glib/arrow-glib/basic-array-classes.html#garrow-array-import
  * garrow_array_export()
    https://arrow.apache.org/docs/c_glib/arrow-glib/basic-array-classes.html#garrow-array-export
  * garrow_data_type_export()
    https://arrow.apache.org/docs/c_glib/arrow-glib/basic-data-type-classes.html#garrow-data-type-export
  * garrow_data_type_import()
    https://arrow.apache.org/docs/c_glib/arrow-glib/basic-data-type-classes.html#garrow-data-type-import


Here is an use-case of them:

  * Red Arrow DuckDB
