ParseFromArray vs ParseFromString

[sahil goyal]

What is the difference between ParseFromArray and ParseFromString? Is there any limitation on the data, how much there API's can serialize and de-serialize?

ParseFromString(value) is the same as ParseFromArray(value.data(), value.size()). Protobuf uses int32 to store size/length information, so the maximum a message can be is 2G bytes. The library will start to give warnings once the size exceeds a much smaller limit though:
