python 2.7 - Will using memcache reduce my instance memory? -

-

i'm running soft memory errors on google app engine app because of high memory usage. number of large objects driving memory usage sky high.

i thought perhaps if set , recalled them memcache maybe might reduce overall memory usage. reading through docs doesn't seem case, , benefit of memcache reduce hrd queries.

does memcache impact overall memory positively or negatively?

edit: know can upgrade instance class f2 i'm trying see if can remain on least expensive while reducing memory.

moving objects , memcache have no impact on memory unless destroy these objects in java code or empty collections.

a bigger problem memcache entities limited 1mb, , memcache not guaranteed. first of these limitations means cannot push large objects memcache.

the second limitations means cannot replace, example, hashmap memcache - it's impossible tell if getvalue() returns null because object not present or because bumped out of memcache. have make call each time datastore see if object not present.
