Annotating existing properties as [Indexed] vs schema version

[bdach]

Assume I have the following realm model (simplified):

public class ScoreInfo : RealmObject
{
    [PrimaryKey]
    public Guid ID { get; set; }

    public string Hash { get; set; }
}

I want to annotate Hash with [Indexed] for faster lookups. Is it necessary, recommended, or required to increment the SchemaVersion in the RealmConfiguration after applying such a change?

I tried to look for an answer to this in docs and only found indexed fields mentioned here which is not explicit on the matter at hand. The docs on changing schema also do not mention index annotations in any way.

Adding and removing indexes does not require bumping the schema version as it doesn't necessitate migrations (the data is still the same, we just build an index for faster lookups).

Thanks for the prompt reply!

Is there any documentation as to when the index is built (and if removing the indexed attribute, when/how it is removed)?

[nirinchev]

We don't have docs for this as far as I know. But the changes are applied synchronously when the realm is opened.
