hi,
    I have interested in apache-calcite, I want use apache-calcite in my 
distributed data query(multi compute nodes).
  
    example\csv in apache-calcite is very simple for use, It just used as 
single node.
    apache drill/apache Kylin/apache Phoenix are very heavy for learning 
apache-calcite.
    Does there has any simple apache-calcite example for begin develop a 
distributed execute Engine, thanks. 
    eg: some cvs files in hdfs (5 node), I wan query it in 10 pc nodes.
  
    Thanks.
