1. shard

   모든 서버 작업은 끝이 났다. 마지막으로 shard key를 설정하면 된다.

    use admin
   
    db.runCommand({enablesharding:'DB_NAME'});
    db.runCommand({shardcollection:'DB_NAME.TABLE_ONE', key:{ID:'hashed'}}); 
    db.runCommand({shardcollection:'DB_NAME.TABLE_TWO', key:{ID:'1'}});
    db.runCommand({shardcollection:'DB_NAME.TABLE_THREE', key:{ID:1, name:1}});
