Hi all,

let's say you have a large number of messages of the same type in
memory. One field of this type is marked as repeated:
message Test {
        repeated uint64 foo = 1;
}
RepeatedField defines the default size to be 4. If most of my objects
have 5 foos, I waste a lot of memory.

Is it possible to make kInitialSize into a template parameter of
RepeatedField? Thatway I could have different default sizes for
different message types. The message description could provide an
option for setting a new default length:
message Test {
        repeated uint64 foo = 1 [default_size=5];
}

Cheers,
  Thorsten
