Paul (pquerna),
Did I see a commit flash past from you working on that a while ago ?
Or is my memory way off ?
As I am about to do some work here* - and am wondering if this should
be done properly or as a one off hack. (libketama has some funny exit
codes, etc - so it takes a bit of wrapping),
To use libketama, you should just be able to use this callback function
in apr_memcache trunk, to do server selection:
* Custom Server Select callback function prototype.
* @param baton user selected baton
* @param mc memcache instance, use mc->live_servers to select a node
* @param hash hash of the selected key.
typedef apr_memcache_server_t* (*apr_memcache_server_func)(void *baton,
apr_memcache_t *mc,
const apr_uint32_t hash);
If you need any other callbacks added, just let us know and we can look
into getting them into trunk. I would like to make apr_memcache
behaviors more plugable, rather than people having to patch it.....
On libketama, you need to be aware of issues with flapping nodes and
cache consistency issues... Its definitely something I wouldn't want
apr_memcache using by default.
Thanks,
