- I have in mind the following general definition for logging :
-
- Logging is an append-only storage semantics. The unit of logging
- is the record. Write accesses append records to the end of the log.
- A log record may become obsolete. Useless records are compacted
- out of the log when possible. Other write accesses are forbidden.
-
- I think that all the cases I mention fit with this definition.
