A Unified SQL Layer with Hive
Developers building SQL applications should not have to choose between different SQL solutions, each with its own strengths and weakness. We envision a unified SQL layer, enabled by Hive’s support for SQL:2011, that transparently uses the appropriate engine based on the query access pattern.
This combination provides a single SQL dialect and single connector. Data architects and DBAs can determine where data should be stored based on usage patterns without burdening user applications with the need to connect to multiple systems.
