When using Memcached for caching, there may be scenarios where you need to clear all data from the cache. This operation can be useful during:
C# has several libraries that provide interfaces to interact with Memcached, one of them being EnyimMemcached.
First, install it through NuGet package manager:
Install-Package EnyimMemcached
Here's how to flush all data from Memcached using this library:
using Enyim.Caching; // Create a new MemcachedClient instance MemcachedClient client = new MemcachedClient(); // Flush all data client.FlushAll();
The FlushAll
function sends a flush command to the Memcached server, instructing it to clear all data.
FlushAll
operation sparingly as it clears all data from the entire cache, which could impact performance if the cache has to be repopulated from the database.FlushAll
operation to help in debugging and tracing potential issues.FlushAll
during peak traffic times: As this operation is quite disruptive, try to schedule such operations during off-peak hours.FlushAll
: If you find yourself frequently needing to flush the cache, it may indicate a problem with how data is being cached or invalidated.Q: Will the FlushAll
command remove all items from all servers in a Memcached cluster?
A: Yes, the FlushAll
command will remove all items from all servers in a Memcached cluster.
Q: Can I restore the items after running a FlushAll
command?
A: No, once items are removed from the cache using FlushAll
, they cannot be restored.
