Performance problems with rather big db - Hibernate Console view can't process rather big amount of tables ---------------------------------------------------------------------------------------------------------- Key: JBIDE-2173 URL: https://jira.jboss.org/jira/browse/JBIDE-2173 Project: Tools (JBoss Tools) Issue Type: Bug Components: Hibernate Reporter: Vitali Yemialyanchyk Assignee: Max Rydahl Andersen Priority: Minor Fix For: 3.1.0.CR2 Attachments: HSQLDB_JUnit_Screens.zip, JBIDE-2173_20081119.zip, JBIDE-2173_20100121.zip, JBIDE-2173_20100126.zip, JBIDE-2173_20100126_2.zip, JBIDE-2173_20100127_patch.zip, MySQL_JUnit_Screens.zip, Oracle_JUnit_Screens.zip, Postgre_JUnit_Screens.zip For test purposes I create org.hibernate.eclipse.console.test -> org.hibernate.eclipse.console.db.test.BigDBCreateTest - the main goal of this class is creation test database with specified number of related tables. Then with help of BigDBCreateTest I create a big enough databases with different number of tables in it. And then I try to test hibernate plugins performance. I create a configuration for my test db. In Hibernate Console I try to expand tree. Here is a time: 200 tables in db - takes 40 seconds; 300 tables in db - takes 2 minutes 45 seconds; 500 tables in db - too long I do not get results. Remark: I use MySQL as test db. 3000 tables - too much for MySQL. Also - it is intresting - when I create such big db - I try to expand Hibernate Console tree - I get MySQL exception - but in this case Hibernate Console display all items quickly! JBIDE-2162 is related; JBIDE-2163 & JBIDE-2164 are related by implication - till the moment when I have fixed its in my test environment - I can't see performance problems.
