[jira] [Resolved] (IGNITE-9201) Immutables derived values aren't

------------------------------------
Resolution: Not A Problem
> Immutables derived values aren't properly set on deserialization
> ----------------------------------------------------------------
>
> Key: IGNITE-9201
> URL: https://issues.apache.org/jira/browse/IGNITE-9201
> Project: Ignite
> Issue Type: Bug
> Components: cache
> Affects Versions: 2.6
> Reporter: Glen Takahashi
> Priority: Major
>
> When using the @Value.Derived annotation for an Immutables class, the Immutables-generated class implementation sets those values as `transient` because they are meant to be constructed by the builder.
> Because Ignite ignores transient variables when marshalling to a BinaryObject, and also because Ignite uses reflection to unmarshal from a BinaryObject, those transient variables are left uninitialized in the returned Immutables object from the cache.
> One idea would be instead to use an ObjectMapper and store a string/json representation in the cache and deserialize manually with the ObjectMapper, but was hoping there would be a better way to natively support Immutables and/or Jackson-serializable objects by not using Reflection in some cases.
