Alec Posney updated ARROW-2090: ------------------------------- Summary: [Python] Add context manager methods to ParquetWriter (was: Add context manager methods to ParquetWriter) > [Python] Add context manager methods to ParquetWriter > ----------------------------------------------------- > > Key: ARROW-2090 > URL: https://issues.apache.org/jira/browse/ARROW-2090 > Project: Apache Arrow > Issue Type: Improvement > Components: Python > Reporter: Alec Posney > Priority: Minor > Labels: pull-request-available > > Add the ability to use python {{with}} syntax on the {{ParquetWriter}} object. > For example: > {code:python} > with pq.ParquetWriter(foo, schema) as writer: > writer.write_table(table) > {code} > The benefit of this syntax is that it removes the chances of you writing out > a partial (invalid) parquet file, which is currently possible if you forget > to call the close method, or more likely the close method is not called due > to an exception being thrown. > It should still be possible to use the previous syntax for backwards > compatibility and fine grained control reasons. > Similarly, the {{parquet}} module level {{write_table}} method should be able > to use the new syntax without changing previous behaviour. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
