Renaming a public constants is a backward incompatible change. How about keeping the original constants as an alias for the new constants, mark and document that they are deprecated with a reference to the new names, and use the new constants in the file.

Totally forgot about that, fixed.

Now, it seems that the local constants MINIMUM_RECORD_COUNT_FOR_CHECK and MAXIMUM_RECORD_COUNT_FOR_CHECK are not needed anymore. Could you please remove them? (recordCountForNextMemCheck should be initialized by using the corresponding value from ParquetProperties.)

👍 I also removed the unused rowGroupSize instance variable

@rgruener, @gszadovszky, there's already an open PR for this and a duplicate issue: PARQUET-869. The PR is #470, which I've updated for @pradeepg26. Sorry for the confusion and duplication, but I'd like to continue with that one since the contribution from Pradeep was made earlier. I just shouldn't commit it myself because I ended up making the changes I requested when I backported this to our Parquet version. |

Ah, I wish I saw that before. The duplicate JIRA issue should probably be closed. I am fine having that one continue, we just would like this change to get into the next release since we have been patching this in ourselves. |

Adds way to control the min/max amount of rows to pass when checking on the block size instead of hard coded values.
