Hana preload memory option

When we originally converted to BW on HANA, I set some specific tables to automatically load to memory at database startup. Recently, though, I set the option for these tables to load NONE to memory on database startup. I even look in SYS.TABLES and see the column IS_PRELOAD as FALSE for these tables. But when we restart the database, these tables are still loading FULL to memory, even before any queries are ran. Any ideas?

Thanks,

Dustin

    Hello Dustin,

    HANA tries to reload previously loaded columns asynchronously and it is also based on previous load information for improved performance on system restart. I suppose there are no other tables which were used before previous restart significantly hence you see that these tables are loaded even though you have mentioned otherwise in table metadata.

    BR,

    Dustin:

    1) What is your version?

    2) Please unload them manually once, then check.

    Regards.
