 Hi,

We were using memcached and developed a java api to flush the cache.

I have changed my set with membase cluser with 2 nodes and using moxi i am accessing membase cluster into my program. But when we try to use the same flush api to flush the cache , it is not flushing cache from all the nodes.

Could you guide us to flush the cache from all the nodes by using membase api

Thanks,

Pradeep

 Pradeep, there are currently some known issues with the memcached 'flush_all' command not working properly.  We've got open bugs and I will follow up with our engineering team to see when it can be fixed.

 

In the meantime, you can pretty easily remove all the data from a Membase bucket by simply shutting down the service, deleting the database files and then restarting.  

 

Let me know if that helps

 

Perry

Hi Perry,

Is there a way I can flush a vBucket?

Background: I need to group my cache by modules, and be able to refresh the cache of that module on demand.
I can code my CacheManager to have multiple MemcachedClient instances and tag them to a vBucket, dedicated for a module.

mc1 = new MemcachedClient(baseURIs, "module1", "");
mc2 = new MemcachedClient(baseURIs, "module2", "");

Thanks
Abhilash
