All, I understood that DataSourceV2 supports Transactional write and wanted to implement that in JDBC DataSource V2 connector ( PR#25211 <https://github.com/apache/spark/pull/25211> ).
Don't see how this is feasible for JDBC based connector. The FW suggest that EXECUTOR send a commit message to DRIVER, and actual commit should only be done by DRIVER after receiving all commit confirmations. This will not work for JDBC as commits have to happen on the JDBC Connection which is maintained by the EXECUTORS and JDBCConnection is not serializable that it can be sent to the DRIVER. Am i right in thinking that this cannot be supported for JDBC? My goal is to either fully write or roll back the dataframe write operation. Thanks in advance for your help. Regards, Shiv
