filter or select by property other than id

[boris-jenicek]

Hi, again, what is the best way to select an entity by other property than id?

For example, we have one on one relations between two objects

object A 
    {
    id,
    name,
    date,
    ...etc,
    }

object B 
    {
    id,
    aObjectId,
    name,
    date,
    ...etc,
    }

list of objects A and list objects B has separate stores, we need to select an entity from store B by property aObjectId, what would be the best way to do it? There would be around 10 000 entities of each.

We'll add a selectEntityByPredicate selector.

that sounds good, do you maybe already have any plan for the release date? I was thinking about speed and memory, I see entities are mapped nicely to have id as the key so they have fast access without iterating through the whole list.

I got the idea to use UI entities for the purpose and store them just like a foreign key column to preserve the speed. But that would be a misuse of UI entities and it would be necessary to sync both lists.
