11.6.6. Hot Rod Get Operation
A Hot Rod
Get operation uses the following request format:
| Field | Data Type | Details |
|---|---|---|
| Header | - | - |
| Key Length | vInt | Contains the length of the key. The vInt data type is used because of its size (up to 5 bytes), which is larger than the size of Integer.MAX_VALUE. However, Java disallows single array sizes to exceed the size of Integer.MAX_VALUE. As a result, this vInt is also limited to the maximum size of Integer.MAX_VALUE. |
| Key | Byte array | Contains a key, the corresponding value of which is requested. |
The response header for this operation contains one of the following response statuses:
| Response Status | Details |
|---|---|
| 0x00 | Successful operation. |

The format of the
