Summary: Enable better control over Parquet writing
Key: IMPALA-7936
URL: https://issues.apache.org/jira/browse/IMPALA-7936
Project: IMPALA
Issue Type: Improvement
Reporter: Zoltán Borók-Nagy
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.
