Druid Brokers accept queries and farm them out to the rest of the cluster. They also optionally maintain an
in-memory query cache. These servers benefit greatly from CPU and RAM.
Druid Brokers 可以接受查询,并且将接受的查询发送到集群中处理。同时他们也负责维护内存中的查询缓存, 常来说越大的 CPU, RAM 越好。
In this example, we will be deploying the equivalent of one AWS [m5.2xlarge](https://aws.amazon.com/ec2/instance-types/m5/) instance.

You can consider co-locating any open source UIs or query libraries on the same server that the Broker is running on.
你也可以考虑在运行 Broker 进程的查询服务器上部署任何开源的 UI 或者查询库。
Example Query server configurations that have been sized for this hardware can be found under `conf/druid/cluster/query`.
