Hi guys, Our previous fragment interface has some problems, so it is improved in https://issues.apache.org/jira/browse/TAJO-2146.
Highlights are - Recaped Fragment to have a consistent interface. - Abstracted common variables of Fragment. - Added FragmentSerde for user-defined fragment serialization and deserialization - Changed fragment configuration properties in storage-default.xml. A fragment and a fragment serde are specified for each tablespace. For more details, please our updated wiki at https://cwiki.apache.org/confluence/display/TAJO/Adding+a+new+Tablespace. Thanks, Jihoon
