From 5a1cbdc6f1e32be7b8430924a1125422d8457584 Mon Sep 17 00:00:00 2001 From: Brion Vibber Date: Thu, 4 Feb 2010 11:06:01 -0800 Subject: Add time-based cutoffs for public tag cloud, favorited lists to speed up those queries. Defaulting to only looking at last 90 days of activity, can be adjusted up or down. $config['tag']['cutoff'] = 86400 * 90; $config['popular']['cutoff'] = 86400 * 90; Per-user and per-group tag clouds do not use the cutoff (and it doesn't help with indexing on them). --- actions/publictagcloud.php | 3 +++ 1 file changed, 3 insertions(+) (limited to 'actions/publictagcloud.php') diff --git a/actions/publictagcloud.php b/actions/publictagcloud.php index 9e4478dbb..9993b2d3f 100644 --- a/actions/publictagcloud.php +++ b/actions/publictagcloud.php @@ -106,7 +106,10 @@ class PublictagcloudAction extends Action #Add the aggregated columns... $tags->selectAdd('max(notice_id) as last_notice_id'); $calc = common_sql_weight('created', common_config('tag', 'dropoff')); + $cutoff = sprintf("notice_tag.created > '%s'", + common_sql_date(time() - common_config('tag', 'cutoff'))); $tags->selectAdd($calc .
