1. Distributed without a single point

2. Horizontal expansion

3. Low latency, message push mode

4. Load balancing and multicast-style message delivery

5. Suitable for both high throughput and task-oriented load

6. Based on memory, if the quota exceeds, it can be stored to disk.

7. Consumers find producers through run-time service discovery

8. Have a simple management interface

Nsq consists of three parts, nsqd,nsqadmin,nsqlookupd

Nsqd: receives and sends messages to clients, usually deployed with applications, does not communicate with each other, and sends heartbeats to all nslookupd processes

Nsqlookupd: manage topology information and provide final consistency service

Nsqadmin: management Interfac

Consumer, producer of topic from nsqlookupd
