U4-4292 - RelationService is slow and doesn't appear to be caching properly (v6.1.6)

Created by Scott McClannahan 24 Feb 2014, 18:37:18 Updated by Shannon Deminick 26 Jun 2017, 05:41:32

It appears that the RelationService API performs very slow, compared to other APIs such as ContentService and/or uQuery. For example, loading a list of 50 relations takes about 15 seconds.

Here is an example of the code: var allRelations = _relationService.GetAllRelations().ToList();

I've also tried filtering down relations by type and/or id like this: var dealLocationRelationType = _relationService.GetRelationTypeByAlias(RELATIONTYPE_DEAL_LOCATION); var allDealLocationRelations = _relationService.GetAllRelationsByRelationType(dealLocationRelationType).ToList();

I believe that this is an issue with the underlying code because I am seeing nearly 100 queries executing against the database, however if this is an implementation issue, then I would suggest that we update the documentation as there is very little on the RelationShip API service.

Same here. Relation service is awfully slow for large content setups. For me ApplicationContext.Current.Services.RelationService.GetAllRelationsByRelationType(1).ToList(); executes for 22(!) seconds
