json_generator_set_root() not memory efficient
If I understand it correctly, calling
json_generator_set_root() makes a copy of the passed-in
JsonNode, which means it'll use twice more memory.
Is that correct observation?
I'd like to create (possibly large)
JsonBuilder and then pass this to
JsonGenerator to make it a string, which will be passed over network to the destination. As it may mean the (possibly large)
JsonObject-s, I'd prefer to avoid duplication of the data in the memory.
I think the current workaround would be to not use
JsonBuilder at all, rather create the root
JsonNode, set it immediately to the
JsonGenerator, free the node and read back the one inside the generator and then fill the node with the object (again, without using
JsonBuilder). Am I right?
