Sergey Shelukhin commented on HIVE-4888:
----------------------------------------
There doesn't appear to be any equivalent of Long.parse in DN/JDO. Casts are
not it.
I am playing with writing a DN SQLMethod plugin, but it would only work if DN
is backed by SQL store as far as I see. I will file DN jira. HIVE-4051 makes
pushdown work for SQL, so I might end up doing HIVE-4914 instead and having
server decide to do pushdown to SQL or no pushdown for JDOQL for those. Depends
on how seamless the plugin would be.

> 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.
