Hello Team,
I would like to know how the changes that happens in the HANA memory is saved to the disk. From my understanding the data is loaded from source system like ERP, BW etc to the HANA data volumes and then the data is loaded from the data volumes to the Server Memory.
And whatever changes are happening to the records on the HANA memory is captured at the log volume so incase the the server memory goes down due to power loss etc we can recover the HANA system from the data volumes and also applying the changes saved at the log volumes. The question is are the changes saved to disk as well, if so how does HANA application handle it? Are the changes saved at the log volume applied from the logs to disks or the changes at the Server memory itself flushed after sometime to disk? What is this process called? Savepoint is the procedure by which the changes are saved in the log volumes. Do we have a similar teminology for saving data to disk?
Thanks for the clarification.
Thanks and Regards,
Archana
