wanted know if there better way solve problem having. here flow: our client code understands protocol buffers (protobuf). on server side, our gateway gets protobuf , puts onto kafka. now avrò recommended encoding scheme, put specific protobuf within avro (as byte array) , put onto message bus. reason avoid having entire protobuf->avro conversion. on consumer side, reads avro message, gets protobuf out of , works on that. how reliable protobuf kafka? there lot of people using it? advantages/disadvantages of using kafka protobuf? is there better way handle our use case/scenario? thanks kafka doesn't differentiate between encoding schemes since @ end every message flows in , out of kafka binary . both proto-buff , avro binary based encoding schemes, why want wrap proto-buff inside avro schema, when can directly put proto-buff message kafka?

is possible find size of item_t through pointer? typedef struct item { char x; char y; char life; }item_t; void main (void) { item_t test; void *ptr = &test; printf("%d\n",sizeof(ptr)); } return: 8 not if ptr of type void* -- shouldn't be. you can't dereference void* pointer. can convert other pointer type , dereference result of conversion. can useful, more should define pointer correct type in first place. if want pointer item_t object, use item_t* pointer: item_t test; item_t *ptr = &test; printf("%zu\n", sizeof(*ptr)); this give size of single item_t object, because that's type ptr points to. if ptr uninitialized, or null pointer, you'll same result, because operand of sizeof not evaluated (with 1 exception doesn't apply here). if ptr initialized point initial element of array of item_t objects: ptr = malloc(42 * sizeof *ptr); sizeof *ptr still give size of 1 of them. the sizeof
