HI ,
I wanted to know how distributed hashing works and exact workflow of
any of the GET/STORE/DELETE .
I have gone through the code in memcached.c and there is a pool of
connections for requests . I'm finding it tedious to understand.
- thread.c which calls item_get () which uses a hash functions from
hash.c (I think this is hash returns IP of the server)
- item_get() function again calls do_item_get() from items.c which
calls assoc_find() .( this hash for which bucket the item has to go )
This is what I understood from the material i have gone through . libevent
has a pool of threads and when ever there is a request from client it
randomly sent to a server A and from there after hashing the request is
sent to proper server B.
I just want to know what happens in these two functions and when any of the
GET/STORE/DELETE
is called how a request is passed to the correct server where key item is
present from client side . Please correct me if I'm wrong in understanding
concepts.
Thanks
Mothiki
