> Currently, Tajo uses HDFS as a primary storage. But, as a data warehouse system, Tajo should easily support various data sources.
> For this, I propose a generic storage handler interface that provides common storage methods as follows:
> * splitting input data
> * locality
> * accessing catalog (if providing)
> * creating a table
> * removing a table
> * adding default table properties and validating properties
> * committing, rollback, and clean up output tables
> * getting table physical information like table volumes and others
> * managing connection pool for connection-based storages
> * adding storage-specified rewrite rules
> * adding hooks for query phases
> * physical properties like instant random access, indexible, read throughput, and write throughput
