#562 Reduce the frequency for database updating Issue created by zhuoyuan-liu All read requests such as

config

and

query read

would update the database about the node info. However, these updates would become a bottleneck for database performance. I understand that many functions reply on the last seen timestamps, but it would be not scaleable with such heavily written requests to the database. I have two ideas, one is to store these data in Redis/memory and update them periodically. Another is that we process these changes async. In our test, we only have 3 req/s but the latency between database and osctrl is around 50ms. Looking forward to hearing from your idea. jmpsec/osctrl
