    .proto Type

      Notes C++ Type Java Type
    double    double  double
    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
    int64 Uses variable-length encoding. Inefficient for encoding negative numbers – if your field is likely to have negative values, use sint64 instead.  int64  long
    uint32 Uses variable-length encoding.  uint32  int
    uint64 Uses variable-length encoding.  uint64  long
    sint32 Uses variable-length encoding. Signed int value. These more efficiently encode negative numbers than regular int32s.  int32  int
    sint64 Uses variable-length encoding. Signed int value. These more efficiently encode negative numbers than regular int64s.   int64  long
    fixed32 Always four bytes. More efficient than uint32 if values are often greater than 228  uint32  int
    fixed64 Always eight bytes. More efficient than uint64 if values are often greater than 256.  uint64  long
    sfixed32 Always four bytes.  int32  int
    sfixed64 Always eight bytes.  int64  long
    bool    bool  boolean
    string A string must always contain UTF-8 encoded or 7-bit ASCII text.  string  String
    bytes May contain any arbitrary sequence of bytes. string ByteString
