Hi folks,
It is my understanding that when replicating SAP tables from SAP Oracle db to HANA sidecar db we are able to store tables in HANA using much less physical disk space due to compression.
Now in contrast we are taking one of our SAP Oracle db's and converting to SAP directly on HANA (No sidecar db and no replication involved). Some of the consultants are saying in this case the tables that were in Oracle will now take up to 3 times more disk space on the SAP on HANA db. Can somebody confirm if this is true?
Thanks,
-Patrick
PS: I wonder if they are mistaken and thinking of memory consumption and delta merge process.
