Alexander Kolbasov commented on HIVE-20306:
-------------------------------------------

[~aihuaxu] Here is a summary of my changes:
 # I changed Thrift definition to move \{catalog, dbName, tableName}from spec 
sytucture to request structure

 # Updated RawStore API to avoid exposing directSQL parameters at the API level 
- it is now strictly internal business of ObjectSTore
 # Added extra unit tests
 # Modified equals() method for the new key class used in multimap - previous 
equals() was using hashCode for equality.

> Implement projection spec for fetching only requested fields from partitions
