From f246b8f2d7a7b26c0d5b5ae8847a537e5ebbb125 Mon Sep 17 00:00:00 2001 From: Evan Prodromou Date: Mon, 15 Sep 2008 02:56:16 -0400 Subject: cache noticesWithFriends in memcached noticesWithFriends is turning out to be one of our most expensive queries. The join is costly, and this method is hit over and over and over by desktop clients and other API users. So, I've added a first pass at caching the results. I store a "window" of notices -- equal to the first 3 pages of notices, plus one for pagination -- in the memcached cache. If with-friends notices are requests, I fetch the whole window out of the cache and grab the slice requested. If the requested notices are outside the window, we just do the query. If there's nothing in the cache, we request the window and store it, then return a slice. I had to add a NoticeWrapper class that works like DB_DataObject (well, just the fetch() part...) but just holds an array of notices instead of a DB cursor. Finally, saving a new notice blows away the caches for subscribed users. darcs-hash:20080915065616-84dde-1b1e814c2294498a10b763b779cbb62c3f96aa84.gz --- lib/common.php | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) (limited to 'lib/common.php') diff --git a/lib/common.php b/lib/common.php index 80aab806f..1aa60fc42 100644 --- a/lib/common.php +++ b/lib/common.php @@ -97,7 +97,11 @@ $config = 'daemon' => array('piddir' => '/var/run', 'user' => false, - 'group' => false) + 'group' => false), + 'memcached' => + array('enabled' => false, + 'server' => 'localhost', + 'port' => 11211) ); $config['db'] = &PEAR::getStaticProperty('DB_DataObject','options'); -- cgit v1.2.3-54-g00ecf
