We can store live C structures as records in #LMDB, using a fixed-address memory map so that the address range of the map stays constant. There's a serialization cost to aggregate any pointer-based fields, but zero deserialization cost.
E.g.,
typedef struct foo {
char *name;
char *phone;
} foo;
foo rec1 = {"joe", "5551212"};
Must be stored as:
