Gabor Szadovszky commented on PARQUET-1580:
-------------------------------------------
[~natang.salgia], I would rather not backport it to 1.10.1. This is an
improvement/feature not a bug fix. We need add the required changes only into a
patch release so we have a lower risk that we introduce a regression.

> Now that the specification with respect to page level checksums has been
> clarified (see https://jira.apache.org/jira/browse/PARQUET-1539), we can
> actually implement it. What needs to be done:
> * Implement calculating and writing checksums on write path
> * Implement checksum validation on read path
> * Make writing out checksums and validation on reads optional (default off)
> * Implement tests
