> Project: Apache Hudi
> Issue Type: Task
> Reporter: Sagar Sumit
> Assignee: Sagar Sumit
> Priority: Major
>
> Transaction Manager should be database timeline-aware and return a
> transaction instance when a transaction is started, which can be used with
> dataframe writes as below.
> {code:java}
> val transaction = HoodieTransactionManager.beginTransaction()
> // similar to catalog.addTableToTransaction and execute the write. // Then
> pass the control to
> HoodieTransactionManager.df1.write.format("hudi").withTransaction(transaction).options(opts1).save(basePath1)
> // Same as above. If this failed, then rollback and pass the control to
> HoodieTransactionManager.// HoodieTransactionManager will rollback all
> previous transactions associated with transaction
> id.df2.write.format("hudi").withTransaction(transaction).options(opts2).save(basePath2)
>
> // All success, go ahead and commit or finish rollback (ROLLED_BACK state on
> timeline is written in that case)transaction.commit() {code}
