From f665901e3c0930fb8b3741f6bc6f6a15dd0343f6 Mon Sep 17 00:00:00 2001 From: Eugen Rochko Date: Sun, 6 Oct 2019 22:11:17 +0200 Subject: Fix performance of home feed regeneration (#12084) Fetching statuses from all followed accounts at once takes too long within Postgres. Fetching them one by one and merging in Ruby could be a lot less resource-intensive Because the query for dynamically fetching the home timeline is so heavy, we can no longer offer it when the home timeline is missing --- app/models/home_feed.rb | 16 ++-------------- 1 file changed, 2 insertions(+), 14 deletions(-) (limited to 'app/models/home_feed.rb') diff --git a/app/models/home_feed.rb b/app/models/home_feed.rb index ba7564983..1fd506138 100644 --- a/app/models/home_feed.rb +++ b/app/models/home_feed.rb @@ -7,19 +7,7 @@ class HomeFeed < Feed @account = account end - def get(limit, max_id = nil, since_id = nil, min_id = nil) - if redis.exists("account:#{@account.id}:regeneration") - from_database(limit, max_id, since_id, min_id) - else - super - end - end - - private - - def from_database(limit, max_id, since_id, min_id) - Status.as_home_timeline(@account) - .paginate_by_id(limit, max_id: max_id, since_id: since_id, min_id: min_id) - .reject { |status| FeedManager.instance.filter?(:home, status, @account.id) } + def regenerating? + redis.exists("account:#{@id}:regeneration") end end -- cgit
