.proto Type Notes C++ Type Java Type Python Type
double double double float
float float float float
int32 Uses variable-length encoding. Inefficient for encoding negative numbers – if your field is likely to have negative values, use sint32 instead. int32 int int
int64 Uses variable-length encoding. Inefficient for encoding negative numbers – if your field is likely to have negative values, use sint64 instead. int64 long int/long
uint32 Uses variable-length encoding. uint32 int int/long
uint64 Uses variable-length encoding. uint64 long int/long
sint32 Uses variable-length encoding. Signed int value. These more efficiently encode negative numbers than regular int32s. int32 int int
sint64 Uses variable-length encoding. Signed int value. These more efficiently encode negative numbers than regular int64s. int64 long int/long
fixed32 Always four bytes. More efficient than uint32 if values are often greater than 2^28. uint32 int int
fixed64 Always eight bytes. More efficient than uint64 if values are often greater than 2^56. uint64 long int/long
sfixed32 Always four bytes. int32 int int
sfixed64 Always eight bytes. int64 long int/long
bool bool boolean boolean
string A string must always contain UTF-8 encoded or 7-bit ASCII text. string String str/unicode
bytes May contain any arbitrary sequence of bytes. string ByteString str
