[jira] [Created] (KAFKA-20729) RocksDBTransactionBuffer missing newBaseSnapshotIterator breaks trunk compile

Nilesh Kumar created KAFKA-20729:
------------------------------------

             Summary: RocksDBTransactionBuffer missing newBaseSnapshotIterator breaks trunk compile
                 Key: KAFKA-20729
                 URL: https://issues.apache.org/jira/browse/KAFKA-20729
             Project: Kafka
          Issue Type: Bug
            Reporter: Nilesh Kumar


Follow-up to KAFKA-20493 / #22625.
 
AbstractTransactionBuffer requires newBaseSnapshotIterator() for non-owner (IQ) scans.
InMemoryTransactionBuffer implements it (KAFKA-20494 / #22626), but RocksDBTransactionBuffer does not.
 
Trunk fails to compile:
RocksDBTransactionBuffer is not abstract and does not override
abstract method newBaseSnapshotIterator(...)
 
Fix: implement newBaseSnapshotIterator using RocksDB native snapshots and use it in snapshotScan().
