I have a relational database model This is the basics of my data-config.xml
<entity name="MyMainEntity" pk="pID" query="select ... from [dbo].[TableA] inner join TableB on ..."> <entity name="Entity1" pk="Id1" query="SELECT [Text] Tag from [Table2] where ResourceId = '${MyMainEntity.pId}'"></entity> <entity name="Entity1" pk="Id2" query="SELECT [Text] Tag from [Table2] where ResourceId2 = '${MyMainEntity.pId}'"></entity> <entity name="LibraryItem" pk="ResourceId" query="select SKU FROM [TableB] INNER JOIN ... ON ... INNER JOIN ... ON ... WHERE ... AND ...'"> </entity> </entity> Now, this takes a lot of time. 10000 rows in the first query and then each other inner entities are fetched later (around 10 rows each). If I use a db profiler I see a the three inner entities query running over and over (3 select sentences than again 3 select sentences over and over) This is really not efficient. And the import can run over 40 hrs () Now, What are my options to run it faster . 1. Obviously there is an option to flat the tables to one big table - but that will create a lot of other side effects. I would really like to avoid that extra effort and run solr on my production relational tables. So far it works great out of the box and I am searching here if there is a configuration tweak. 2. If I will flat the rows that - does the schema.xml need to be change too? or the same fields that are multivalued will keep being multivalued. Thanks.
