| 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 6 bytes), which is larger than the size of Integer.MAX_VALUE.

The response header for this operation contains one of the following response statuses:
| Response Status | Details |
