| 32 | Total number of clients that will be connected to the server. |
| 33 | Note that, we do not support dynamic connection for now. It means |

| 39 | Maximal size (bytes) of server queue buffer (~20 GB on default). |
| 40 | Note that the 20 GB is just an upper-bound because DGL uses zero-copy and |
| 41 | it will not allocate 20GB memory at once. |
