I am using StackExchange.Redis to connect to azure redis cache. Everytime I do ConnectionMultiplexer.Connect(....), it creates two connections in the Redis. I am checking the number of connections by using the command "Client List" in Redis. Why is it creating two connections instead of one? How can I create only a single connection?
You need to consider yourself, i.e. the connection of the admin console.

I use https://studio.apollographql.com/sandbox for all my local graphql development.
I can connect to one connection and save operations for the connection.
Is there any way, I can connect to multiple connections and save the operations?
So that, the next time I log in to the studio I can see all the connections and the saved operations.
If possible, could someone suggest any app for mac which does the job? Postman isn't convenient enough for graphql.
Redis is single threaded so do we need to setup connection pool for our redis client apps? I see several libraries use connection pool for redis such as sidekiq, but does it really needed?
Redis server is single threaded. It makes a lot of sense to keep it busy with clients sending multiple requests instead of blocking by making a single request at a time.
I have TCPListener server based on this source code https://gist.github.com/leandrosilva/656054#file-server-cs
I created a server on port 3340. Whenever a client connects to the server, then server waits for the new client connection. When I connect from my Chrome browser to the server, then it seems there are three clients connected (expected only one).
Why it is like that?
Most clients maintain multiple connections in parallel, including more than one connection per server endpoint.
And RFC7230 section-6.4 explains. Multiple connections are typically used to avoid the "head-of-line blocking" problem
How is it possible to ensure that Autobahn only creates a single connection?
Is it possible to either check for existing connections before calling connection.open, or perhaps kill all other connections on connection.onopen?
When using AutobahnJS (which I assume this relates to), you will generally not need to open multiple connections. If your application connects to a single WAMP server, then you can use the single connection for all WAMP actions while it persists, i.e. for all your subscriptions, publishes, registrations and calls.
Assume we have two clients run on different machines, and both generate token from 0.
The Server is very likely to receive same token from the two client.
What will happen if the server receive same token from two different connections ?
And what if the two connection are from same machine ?
Is it possible to STOP query with a diffrent connection from which executes the START Query
TL;DR: Tokens are per connection.
You can send the same token on two different connections. If you look at for example the source of the JS driver, the token is per connection (so two connections can use the same token)
See https://github.com/rethinkdb/rethinkdb/blob/next/drivers/javascript/net.coffee#L43
It you execute a query on connection A, it is not possible to stop it using connection B.
