             Summary: Rename Table conversion methods in TableEnvironment
                 Key: FLINK-2165
                 URL: https://issues.apache.org/jira/browse/FLINK-2165
             Project: Flink
          Issue Type: Improvement
          Components: Table API
    Affects Versions: 0.9
            Reporter: Fabian Hueske
            Priority: Minor
             Fix For: 0.9


The {{TableEnvironment}} provides methods to convert DataSets and DataStreams into Tables and back. These methods are called {{toTable()}}, {{toSet()}}, and {{toStream()}}.

I propose to rename the methods into {{fromDataSet()}}, {{fromDataStream()}}, {{toDataSet()}}, and {{toDataStream()}} for the following reasons:

- {{fromDataSet()}}, {{fromDataStream()}} is closer to the SQL FROM expression
- It allows to add methods such as {{fromCSV()}}, {{fromHCat()}}, {{fromParquet()}}, and so on to the {{TableEnvironment}}
- {{toSet()}} and {{toStream()}} should be renamed for consistency.
