We don't need to write a simple sds-keyval server because the package already provides one for us: In the `sdskv` directory you will find `server.c` and `client.c`, demonstrating
a simple client and server that does a basic put and get of a key/val pair
``` ```
sdskv-server-daemon na+sm testdb:ldb -f sdskv.addr cd sdskv
make
``` ```
That command asks the SDS Keyval server to listen over the "shared memory" In one shell, launch the server (or put it in the background if you want one shell)
interconnect, operate on a database called "testdb" using the "leveldb"
backend, and to write the server address out to a file 'sdskv.addr' that we can For example:
then use for our client. ```
./server
Server running at address na+sm://12829/0
```
Then the client can connect to that server, run its simple exercise, and shut down the server:
```
./client na+sm://12829/0
key 10 had value 99
```
### Exercise ### Exercise
In this exercse instead of putting an integer key and an integer value, I
want you to store a bunch of strings. Turns out a good source of string is in
`/usr/share/dict/words`. Can you prove you stored what you thought you stored?
We provided a simple sds-keyval server in the prior example, but the package
already provides a standalone, full sds-keyval server for us:
```
sdskv-server-daemon na+sm testdb:ldb -f sdskv.addr
```
That command asks the SDS Keyval server to listen over the "shared memory"
interconnect, operate on a database called "testdb" using the "leveldb"
backend, and to write the server address out to a file 'sdskv.addr' that we can
then use for our client.
