Subject [jira] [Updated] (SPARK-25390) data source V2 API refactoring
Date Tue, 25 Sep 2018 15:34:00 GMT

     [ https://issues.apache.org/jira/browse/SPARK-25390?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Wenchen Fan updated SPARK-25390:
--------------------------------
    Description: 
Currently it's not very clear how we should abstract data source v2 API. The abstraction should
be unified between batch and streaming, or similar but have a well-defined difference between
batch and streaming. And the abstraction should also include catalog/table.

An example of the abstraction:
{code}
batch: catalog -> table -> scan
streaming: catalog -> table -> stream -> scan
{code}

We should refactor the data source v2 API according to the abstraction
