[xwiki-devs] XWiki Scalability/Challenge Question

Hello Devs, I am developing an application based on XWiki that is mapping, connecting, relating and graphical disposing movie information in order to make possible to the user explore their trailers. At the beginning with a light data set (<5k movies) the application was running well, but today I started to populate my database (MYSQL) and the application became unusable, the queries is taking more than 5 minutes to complete. Actually, it has more than 15k movies (1 movie = 1 doc) and I need to upload more 100k. I already have checked the cache and performance page but I don't know if they[1][2] solve my problem: I think that is a architecture challenge. My AS IS process is: -User insert a movie, -the application search for the movie and their related films based on its characteristics (a lot of joins and other algorithms) (bottleneck) -the application returns the results as a map; I am wondering if I could use the custom mapping[3] to solve my problem due the fact that the relationship information for each movie, in this first moment, don't need to change often. Each movie has X movies related, sorted by similarity. So, I could create some relationship algorithm that will run scheduled ( 1 time by week) and populate this new table .I am thinking to use dataframe panda of python to talk directlly with mysql and make data analysis, any other suggestion? So I would create a custom map to my relationship movie class, run the algorithm, populate the new table, so my TO BE would be: TO BE -user insert movie info; -simple select on the customtable "MoviesRelated"; -the application returns the results; I would appreciate some opinion. Thank you very much.
