Redis: Cluster Environment & Fail-over

[sreeram.r...@outlook.com]

Hi All,

I'm new to Redis, I'm trying configure Redis environment for high-availablity as below,

Machine 1 : Redis Master & a Sentinel (monitoring Redis master)

Machine 2 : Redis Slave & a Sentinel (monitoring Redis master)

Machine 3 : Redis Slave & a Sentinel (monitoring Redis master)

From application client (StackExchange.Redis), I'm able to connect Redis Master with below config

<redisCacheClient allowAdmin="true" ssl="false" connectTimeout="5000" database="0">

<hosts>

<add host="<Machine 1_IP>" cachePort="6379" />

</hosts>

Now, When my Machine 1 goes down, Sentinels switches the master to either Machine 2 or Machine 3.

1. How will my Application client know that Redis master has been switched?

2. Should I provide all Redis-server IP in Application client's app.config section? 

Please advise.

Thanks.

At best you have a Sentinel-aware Client.
Then you only let it know about the Sentinel IPs and it will
automatically figure out the rest.
