[hibernate-issues] [Hibernate-JIRA] Created: (HHH-3271) Prepare Statement Caching

Prepare Statement Caching ------------------------- Key: HHH-3271 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3271 Project: Hibernate3 Issue Type: Bug Components: core Affects Versions: 3.2.5 Environment: Hibernate 3.2.5, Oracle 10g Reporter: lalit railwani We are using Hibernate 3.2.5 are trying to evaluate hibernate batching vis a vis JDBC batching. As per our results the hibernate batching takes approx 2 times the time taken by JDBC batching. The problem is we need to commit the batches also so in a loop we are commiting the transaction also (batching). But for every new loop hibernate creates new prepared statements i.e. if we have 20 batches 20 prepared statements per table/entity are being created but in case of JDBC the same can be done using 1 prepared statement per table/entity. Hibernate does reuse the prepared statements within a batch but not across batches. If hibernate can reuse these statements it would significantly reduce the timings and would bring the hibernate batching close to jdbc batching. This is happening even after enabling prepare statement caching in the hibernate cfg xml. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
