Re: [hibernate-dev] Link to test case templates

Thanks guys for taking this into consideration. I've seen those negative tweets lately, regarding the JIRA issues and maybe helping people provide more focused unit-tests is for the best.We could integrate those easily into Hibernate main test suite and we can address them more rapidly too. I ne

Re: [hibernate-dev] Apache Trafodion Dialect

That's indeed interesting. It is like a RDBMS that uses Hadoop as the underlying storage engine.I see that others have managed to run the TPC-C suite against Trafodion too: http://hammerora.sourceforge.net/hammerdb_trafodion_oltp.pdf I think this could be a good opportunity for Hibernate to appr

That's a good idea. After I'm done with the first part of my book, I'll review all 5.0 changes and collect them all in one presentation for our local JUG too. Vlad  On Wednesday, October 21, 2015 4:35 PM, Sanne Grinovero wrote: Remind me of this when we meet next week! Happy to wa

[hibernate-dev] Persistence.xml properties are not available when the Hibernate services are bootstrapped

Hi Steven, I'm trying to integrate FlexyPool ( https://github.com/vladmihalcea/flexy-pool ) with Java EE Application servers, and the only work-around I found is to add a new Hibernate ConnectionProvider that extends the DataSourceConnectionProvider and exposes a DataSource proxy, instead of the

[hibernate-dev] Hibernate Metrics support

Hi Steve, I was thinking of having a Metrics gathering API for all sorts of database-related operations: - connection acquiring/lease time- connection wait time- transaction durations- SQL query logger - slow queries threshold- number of queries per transaction threshold Something similar to htt

Re: [hibernate-dev] Hibernate ORM - next steps

From a performance perspective, I'm glad we'll be able to override the EAGER fetching on a query-basis. We could have an UNFETCH directive to do the opposite of the current FETCH one. The bytecode enhancement dirty-checking is also a plus.  Vlad On Friday, May 29, 2015 11:09 AM, Emmanue

[hibernate-dev] Immutable entities read-only caching improvement proposal

[hibernate-dev] hibernate.cache.default_cache_concurrency_strategy has no effect

Hi, Setting the "hibernate.cache.default_cache_concurrency_strategy" property doesn't have any effect. This setting is inspected in AnnotationBinder.prepareDefaultCacheConcurrencyStrategy method, but thatmethod is never called. Here's a test to replicate the issue: https://github.com/vladmihalc

[hibernate-dev] Any change of adding generics to Hibernate specific API

Hi, Although many rely on the Java Persistence API, Hibernate still offers specific features, like mapping a native SQLQuery result set to a DTO: .setResultTransformer(Transformers.aliasToBean(DTO.class)); Is it possible to add TypedQuery and TypedSQLQuery, analogous to the JPA specs, so you can
