Elide

Elide has a simply in-memory store you can play with - and you can register functions (life cycle hooks) that can be called whenever something happens to one of your models.

But the in-memory store is local to a host - and won't work in a distributed fashion.

Elide has a pretty simple high level design:

Elide doesn't care what that something is - it just needs to implement the DataStore and DataStoreTransaction interfaces.

Each DataStore manages one or more models

Datastores tell Elide at startup what models they manage in the populateEntityDictionary function.

That's the gist

Gotcha--I'll look into implementing the DataStore and DataStoreTransaction interfaces then.

I have an entity with

@Enumerated(value = EnumType.STRING)
@ElementCollection(targetClass = RegionName.class)
private Set<RegionName> regions;
private enum RegionName {
    MAIN, RIGHTRAIL
}

Is there a way to create an RSQL filter on regions? module?filter[module]=regions=='MAIN'gives me Parameter value [MAIN] did not match expected type [java.util.Set (n/a)]

We just added a new feature in the latest release for the 'hasmember' operator

The above link provides an example of use.

THere are caveats though in its use - there is a Hibernate bug that prevents it being used for subcollection filters.

We haven't documented this filter operator yet.

Hi there! We're using Hibernate with Elide to build a JSON API and an IdClass to be used as composite primary key for one of the tables. We're seeing an issue with Elide returning just a (what appears to be random) part of the composite key as id in resource identifier objects and also it returns only parts of the composite key as attributes. Is this expected behavior? A workaround we found for this was to use a plain primary key as id for the table and add a constraint on the DB schema level.

Known Issue

It is something we want to add support but haven't had cycles to add this capability

I would be happy to help coach a submission

Thanks much for the confirmation!
