Consider reading/writing directly from BSON straem to Tuple to limit unnecessary object creation (like HashMap) by the MongoDB driver ------------------------------------------------------------------------------------------------------------------------------------- Key: OGM-167 URL: https://hibernate.onjira.com/browse/OGM-167 Project: Hibernate OGM Issue Type: New Feature Components: datastore Reporter: Emmanuel Bernard Priority: Minor GC can slow down reads esp for collections. Many HashMap are created and we suspec the MongoDB driver for Java is the creator (DBObject is a subclass of LinkedHashMap). We could imagine not create these BObject but directly talk to the BSON stream. That would of course be a lot of work to do that right and the MongoDB driver needs to expose BSON without parsing it first. It more a prospective idea. -- This message is automatically generated by JIRA. For more information on JIRA, see: http://www.atlassian.com/software/jira
