Sergey Shelukhin updated HIVE-4888:
-----------------------------------
Attachment: HIVE-4888.on-top-of-4914.patch
preliminary, very simple patch on top of HIVE-4914. The pushdown is added to
SQL path only. JDO path will need datanucleus plugin (or version) that supports
string to number conversion, to work properly with number compares. I have no
machines left to run tests, when I do I will run tests and submit the patch for
Hive QA
> listPartitionsByFilter doesn't support lt/gt/lte/gte

> Filter pushdown could be improved. Based on my experiments there's no
> reasonable way to do it with DN 2.0, due to DN bug in substring and
> Collection.get(int) not being implemented.
> With version as low as 2.1 we can use values.get on partition to extract
> values to compare to. Type compatibility is an issue, but is easy for strings
> and integral values.
