Hi all, Data source v2 is out for a while. During this release, we
migrated most of the streaming sources to the v2 API (SPARK-22911 <https://issues.apache.org/jira/browse/SPARK-22911>) started to migrate file sources (SPARK-23817 <https://issues.apache.org/jira/browse/SPARK-23817>) started to design new features (SPARK-24525 <https://issues.apache.org/jira/browse/SPARK-24252>, SPARK-23521 <https://issues.apache.org/jira/browse/SPARK-23521>) did some refactoring and cleanup (SPARK-23203 <https://issues.apache.org/jira/browse/SPARK-23203>, SPARK-23323 <https://issues.apache.org/jira/browse/SPARK-23323>, SPARK-23325 <https://issues.apache.org/jira/browse/SPARK-23325>, ...) >From these works, we learned a lot and get a clearer picture about how the data source API should work with Spark and developers. As a result, we are proposing SPARK-24882 <https://issues.apache.org/jira/browse/SPARK-24882>, to revisit the entire API and improve it. Please read the design doc attached in the JIRA ticket if you are interested in it. Any comments are appreciated! Thanks Wenchen
