> [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.
