Question:

Explain how you can minimize the Memcached server outages in your Python Development?

Answer:

•  When one instance fails, several of them goes down, this will put larger load on the database server when lost data is reloaded as client make a request. To avoid this, if your code has been written to minimize cache stampedes then it will leave a minimal impact
•  Another way is to bring up an instance of Memcached on a new machine using the lost machines IP address
•  Code is another option to minimize server outages as it gives you the liberty to change the Memcached server list with minimal work
•  Setting timeout value is another option that some Memcached clients implement for Memcached server outage. When your Memcached server goes down, the client will keep trying to send a request till the time-out limit is reached
