Re: Can anyone tell me the benifit of libmemcached pool?
You would use a pool of libmemcached instances in your multithreaded application to avoid initiating, connect, disconnect and destroy each time one of the threads wants to send a request to the memcached cluster. Instead you can get an instance from the pool, use it, and put it back in the pool for other threads to use.. Cheers Trond

Re: Can anyone tell me the benifit of libmemcached pool?
Hi, if I define a memcached pool like this:
memcached_pool_st* pool=memcached_pool("--SERVER=ip:port",config_length);
can I pop memcached_st multiple times use this pool? like:
memcached_st *memc1 = memcached_pool_pop(pool,false,&rc);
memcached_st *memc2 = memcached_pool_pop(pool,false,&rc);
can anywhere I find the detailed explanation of these functions, including the
returen value and parameters?

Re: Can anyone tell me the benifit of libmemcached pool?
Hi, Trond. I have read the man page for the function memcached_pool_pop(), but
I still don't know what's the meaning of the parameter bool block.
I think the libmemcached uses the pool to store the memcached_st, and
memcached_st keeps a connection with each server in the configuration
string.But, can multiple memcached_st be stored in the same pool? Can a
memcached_st be poped multiple times? Does it mean a pool can only keep a long
cnnection with each server in the configuration string.
Thank you for your reply.

If you create a pool with 5 instances and your code tries to pop 6 instances
out of the pool. if you set the block parameter to true, the 6th call to pop
will block until someone push an instance back into the pool.

The pool is used to store memcached_st instances, and you can push and pop
the instances as many times as you like. The idea of the pool is that
instead of doing:
my_little_function_who_needs_memcached() {
create memcached_st
call a libemcached function
destroy memcached_st
}
you would do something like:
my_little_function_who_needs_memcached(pool) {
grab instance from the pool
call a libemcached function
push it back to the pool
}

Re: Can anyone tell me the benifit of libmemcached pool?
hi, Trond. It means I can create many identical memcached_st instances in
advance and push them into a pool. Then, I can pop a memcached_st instance when
needed. How can I use the pool efficiently? Furthermore, I have another
problem. How can I restrict some fixed ips to access the memcached servers
except using iptables? Because the iptables command needs root permission to
execute. Thank you for your reply.

THe normal way do do this is create a single memcached_st instance with the
