TransactionLogRecord
TransactionLogRecord
within the TransactionLog
.
E.g. for a map that would be the map-name and the key. So if a map transactional put is done on some
key, and if later on another put on that key is done, by using the same transaction-log-key, the first
put is overwritten.
If null is returned, this TransactionLogRecord can't be identified and can't be overwritten by a later change.getKey
