Retrieve the server.jar.
curl http://treode.github.io/jars/server.jar -o server.jar
Throughout the discussions, we’ll create database files. To keep it tidy, you may want to make a temporary directory and move the jar there.
Next, initialize the database file, which we’ll call store.3kv.
java -jar server.jar init -host 0xF47F4AA7602F3857 -cell 0x3B69376FF6CE2141 store.3kv
Jul 04, 2015 10:17:18 AM com.treode.disk.DiskEvents changedDisks
INFO: Attached disks: "store.3kv"
We’ll discuss the flags -host and -cell in managing peers. We’ll say more about init in managing disks.
Now start the server.
java -jar server.jar serve -solo store.3kv

We’ll discuss the -solo flag in managing peers, and the serve command in managing disks.
Each table is identified by a 64 bit number, but we want to use symbolic names in our URLs. The schema maps names to IDs.
table <name> {
id: <number>;
};
...more tables...
Upload the schema by performing an HTTP PUT to /admin/treode/schema.
curl -i -w'\n' -XPUT -d@- http://localhost:9990/admin/treode/schema << EOF
table fruit {
id: 1;
};
EOF
HTTP/1.1 200 OK
Content-Length: 0
We will use the fruit table in the examples for read and write, and scan.
