---------------------------------
Summary: Add Table Partitioning
Key: TAJO-283
URL: https://issues.apache.org/jira/browse/TAJO-283
Project: Tajo
Issue Type: New Feature
Components: catalog, physical operator, planner/optimizer
Reporter: Hyunsik Choi
Assignee: Hyunsik Choi
Fix For: 0.8-incubating
Table partitioning gives many facilities to maintain large tables. First of
all, it enables the data management system to prune many input data which are
actually not necessary. In addition, it gives the system more optimization
opportunities that exploit the physical layouts.
Basically, Tajo should follow the RDBMS-style partitioning system, including
range, list, hash, and so on. In order to keep Hive compatibility, we need to
add Hive partition type that does not exists in existing DBMS systems.
