* called back from the RocksDB TransactionDB or OptimisticTransactionDB (C++),
|
|
* we then callback to the appropriate Java method
|

* this enables TransactionNotifier to be implemented in Java.

|

* Unlike RocksJava's Comparator JNI Callback, we do not attempt
|
|
* to reduce Java object allocations by caching the Snapshot object
|
|
* presented to the callback. This could be revisited in future
|
|
* if performance is lacking.
