[Wikidata-bugs] [Maniphest] [Commented On] T205865: Investigate decrease in wikidata dispatch times due to eqiad -> codfw DC switch

[Addshore]

Addshore added a comment.

The "wikibaseDispatchRedisLockManager" uses $wmfMasterServices['redis_lock']

So:

// LockManager Redis
$services['eqiad']['redis_lock'] = [
	'rdb1' => '10.64.0.80',
	'rdb2' => '10.64.16.107',
	'rdb3' => '10.64.48.155'
];
$services['codfw']['redis_lock'] = [
	'rdb1' => '10.192.0.83',
	'rdb2' => '10.192.0.84',
	'rdb3' => '10.192.0.85',
];

I could add some extra timing to the code to determine if the time is being saved on one of the DB queries or during the lock.

I thoughts the DC switch back was happening this week, but as it isn't until next week I should be able to get some more info before it happens.
