The default maxSockets value is Infinity and it determines the limit of number of sockets per host. See official docs: https://nodejs.org/api/http.html#http_agent_maxsockets

You can manually set maxSockets limit using the following code snippet

require('http').globalAgent.maxSockets = 10

globalAgent: Global instance of Agent which is used as the default for all HTTP client requests.

In Node.js, you can set the maximum number of connections per origin. If maxSockets is set, the low-level HTTP client queues requests and assigns them to sockets as they become available.

Ref URL from AWS JS SDK

According to Node.js Doc,

By default set to Infinity. Determines how many concurrent sockets the agent can have open per origin. Origin is either a 'host:port' or 'host:port:localAddress' combination.

Conventionally, they recommend 25~50, I guess.
