Hi,all

I run a cbq command : select * from default , web console show “connections” from 53 to 73
After 15 mins connections still is 73 , never down to 53

And I try using node.js do a N1ql query : select * from default,
It seems same as do cbq command

I wanna know

  1. Why the connections increase and still in 73, not down to 53?
  2. Can I add any code in my node js to decrease connections?

3.Because our company’s MIS tell me too many connections is unusual ,
he ask me notice connections bug and confirm how many connections is healthy,
What’s numbers is healthy connections limit ?

thks for anyone replying
