Subject HCatalog for Key/Value and Document Stores
Date Sat, 07 Jul 2012 03:17:57 GMT
I have a question about the vision of HCatalog and how it fits in with
'NoSQL' projects other than Hive and Pig.

Currently HCatalog enables sharing of data between Pig and Hive users on a
common cluster. This fits the analytics workload when more casual users
consume data in Hive that were created in Pig by a data scientist or
programmer.  There is another workflow that is common in analytics
application development, where data is prepared in Pig or Hive, and
published for consumption in a web application via a specialized store -
key/value, document, etc. or even a relational database.

Is it reasonable to use HCatalog to locate, share and integrate with
key/value, document stores or relational databases? Is this on the map?
Where would one start when learning about building this?
