Hi folks,
I'm looking for specific information on any process that is automatically unloading data from memory. I've experienced HANA memory becoming almost fully used (reaches around 90%) and then magically unloads memory until nearly empty and I'm trying to understand any process that is responsible for this. In HANA Admin guide In section 9.2.1 there is mention of unloading;
"The database may also actively unload tables or individual columns from memory, for example, if a query or other processes in the database require more memory than is currently available. It does this based on a least recently used algorithm."
When memory is full, rather than automatically unloading only one or two of the least used tables it seems to be completely unloading everything. I'd like to find more information on this 'least recently used' algorithm or any related process that could be unloading data from memory.
Thanks,
-Patrick
