--------------------------------
Summary: Design the interface of join enumeration algorithm
Key: TAJO-99
URL: https://issues.apache.org/jira/browse/TAJO-99
Project: Tajo
Issue Type: Sub-task
Components: optimizer
Reporter: Hyunsik Choi
The core feature of cost-based optimizer is cost-based join enumeration
approach. The main objective of this is to find the best join order from lots
of enumerated join trees. In database community, there have been many studies
for join enumeration ways.
It would like to great to provide a generic and pluggable interface for join
enumeration algorithms. It may encourage contributors to implement various join
enumeration ways, and users could choose the best join ordering algorithm for
their purpose.
