---------------------------------
Summary: Generic StorageHandler to provide common storage methods
Key: TAJO-337
URL: https://issues.apache.org/jira/browse/TAJO-337
Project: Tajo
Issue Type: Improvement
Components: catalog, storage
Reporter: Hyunsik Choi
Assignee: Hyunsik Choi
Fix For: 1.0-incubating
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:
* splitting input data
* finding a cluster node which is nearest neighbor to data
* accessing catalog
* creating a table
* removing a table
The above methods are derived from query proecssing mechanism on data sets
stored in HDFS.
Later, we can add easily storage handlers for HBase or other data sources.
