What does StackExchange.Redis do with configured masters / slaves?

I look at StackExchange.Redis and notice that it has functions to automatically detect which of the configured servers are the master and which are the slaves.

I was unable to determine what the StackExchange is actually doing with the configured masters / slaves. Does it always run commands on the Master and only use the configured slaves to fail over? Or is the answer deeper than this?

Any pointers appreciated!

The key point here is the CommandFlags

parameter for each method. However, by default, the majority PreferMaster

; note that write commands automatically go to DemandMaster

. However, if you want to spread the load, you can choose read commands (preferably expensive) for slaves via PreferSlave

and DemandSlave

.



Other things you will allow is to switch master (promote to master) - although this is naturally more invasive.
