The name “Table” is quite misleading here, the table API object Table actually represents a relational query (e.g. Table table = myTableObject.join(…).where(…).select(…)). Thus we use createTemporaryView(String path, Table view) rather than registerTable(String name, Table table) Given a background that registerTable(String name, Table table) is old interface and has been deprecated because the reason I explained. This is a part of FLIP-64[1] Hope I make this clear. Best, Leonard [1] https://cwiki.apache.org/confluence/display/FLINK/FLIP-64%3A+Support+for+Temporary+Objects+in+Table+module
