Collections should be loaded by default using "lazy collection fetch" instead of "extra lazy collection" fetch -------------------------------------------------------------------------------------------------------------- Key: HHH-5686 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5686 Project: Hibernate Core Issue Type: Bug Components: envers Affects Versions: 3.6.0 Environment: Works fine with in-memory database like H2 but for MySQL5 generates too many queries. Reporter: Srinivas Nandina Priority: Minor If an entity has a collection (either entities or components), then loading the collection from audit tables one query is issued per element of collection rather than issuing one query for the whole collection. Because of this while loading huge object graphs from audit tables, large number of queries are issued and taking long time to load the data. Default option to load collections should be changed from "extra lazy collection fetch" to "lazy collection fetch".
