> With the introduction of the Parquet page indexes it became desirable to have more control over how Impala writes Parquet files.
> These configuration options (probably implemented as query options) would be:
>  * enable/disable Parquet page index writing (currently we can do it with a command-line argument)
>  * set page-size limits based on row count
>  * Set truncation length for string values
> They'd enable writing more complete tests for page filtering. They'd be also useful for fine-tuning the page index for better performance.
