Embedded Database Replication

As we all know, embedded databases out perform server databases on every occasion. The problem with embedded databases is that theyre difficult to scale. If I were to create an entire enterprise web application within a single jar file using embedded tomcat and embedded objectdb I would run into problems trying to cluster the data.

LEFT JOIN FETCH over empty embedded collection returns no results

First of all, thank you for promptly implementing JOIN FETCH over nested paths in response to my inquiry a few months ago. However, I have run into one problem: if an embedded collection is empty, but I attempt to LEFT JOIN FETCH all the members of a collection within a (non-existent) member of the first collection, the result of the overall query is an empty set.

slow performance for a complex query

Hi, We have a query that is constructed dynamically, an example is like this: SELECT DISTINCT $1 FROM CDI $1, Organisation $2, Organisation $3 WHERE ((UPPER($1.cdiId) LIKE 'THREAD14%') AND ((($1.parentOrgId='news') OR (($1.parentOrgId=$2.organisationId) AND ($2.parentOrgId='news'))) OR ((($1.parentOrgId=$3.organisationId) AND ($3.parentOrgId=$2.organisationId)) AND ($2.parentOrgId='news')))) I've also tried running the CDI query first and passing the results into the organisation query as follows: ... tried running the CDI query first and passing the results into the organisation query as follows: SELECT DISTINCT $1 ...

How to track memory leak with ObjectDb.

Hello, I suspect some memory leak in my application. ( turning app into OOM very fast ) In fact, some com.objectdb.o.MST objects are retaining a huge % of my heap space. While watching the dump file ( with Eclipse MAT ), i was not able to inspect carrefully the memory leak issue. That's is very hard to debug because of obfuscated objectdb code.

Web Framework Recommendation for leveraging JPA + ObjectDB

Hello dear ObjectDB Community ! First of all let me tell You: I am glad that I have revisited ObjectDB just recently; because with its newly added JPA compliance and affordability, it seems like a natural match to me. I have the following understanding: If I persist standardly against JPA/JDO, I can switch Persistence Engines as I see fit later on ! So that I can easily switch to a true OODBMS like ObjectDB, for instance. ... leverages the JPA standard, but seems to be tied somehow into the Hibernate ORM.
