Optimization Question

One of our uses for your ObjectDB software is in maintaining the current state of a large number of data objects called tracks. These tracks change very frequently over time (every 10-15 seconds is not unreasonable), but they are also very large complex data structures so it's extremely difficult to identify exactly what fields have changed from one update to the next. Currently the following sequence executes when a track update comes in: - If it’s a new track simply add it to the database. #1 2010-06-16 15:41 One of our uses for your ObjectDB software is in maintaining the current state of a large number of data objects cal ...

String representation of a query

Hi, Is it possible to get a JPQL string having a Query object instance? JpaQuery class doesn't have any method like "getQueryString" or "getDatabaseQuery", maybe it's going to be added in near future? It would be very helpfull to have something similiar to Hibernate etc : findAllBooks.unwrap(org.hibernate.Query.class).getQueryString() I would like to measure time of query execution and log that information with JPQL string and parameters map to find and optimize the most ineffective cases. #1 2012-12-18 10:29 Hi, Is it possible to get a JPQL string having a Query object instance?

Hi There I am using ObjectDB 2.6.3. I get the following Exception when I try to read my entities with a query where I have set to use LAZY initalization. It fails when it tries to set a 1:n member (e.g. a Modell has several Artikels) . When I remove the LAZY hint on the query execution it works. Any hints why this can happen?
