Add index to JournalArticle to speed up expiration checks

Details

    Description

      JournalArticleFinder.findByExpirationDate() executes the below query every time it checks to expire articles (default 15):

      SELECT * FROM JournalArticle WHERE (classNameId = 0) AND (status = 0) AND (expirationDate <= '2018-04-06 13:42:57');

      As there is no index on classNameId, status and expirationDate, the database is executing a full table scan to find the entries. With a table size of ~500k, this takes around 10-20 seconds.

      After adding the index, the query finishes almost instantly.
