| Zusammenfassung: | A computer-implemented method according to one aspect includes receiving a request to perform a transaction in persistent memory; determining a correlation between volatile memory address locations in a volatile transaction cache and persistent memory locations in the persistent memory; performing the transaction within the volatile memory address locations of the volatile transaction cache; identifying modified volatile memory address locations in the volatile transaction cache that have been written during the transaction; logging, within the persistent memory, data within the modified volatile memory address locations; copying the data within the modified volatile memory address locations to corresponding persistent memory locations in the persistent memory, utilizing the determined correlation; and removing the logged data from the persistent memory, in response to determining that the copying has completed. |
