Previously, BigDecimal was listed as not needing a serializer. However, when used with an adapter storing the job arguments as JSON, it would get serialized as a simple String, resulting in deserialization also producing a String (instead of a BigDecimal). By using a serializer, we ensure the round trip is safe. During upgrade deployments of applications with multiple replicas making use of BigDecimal job arguments with a queue adapter serializing to JSON, there exists a possible race condition, whereby a "new" replica enqueues a job with an argument serialized using `BigDecimalSerializer`, and an "old" replica fails to deserialize it (as it does not have `BigDecimalSerializer`). Therefore, to ensure safe upgrades, serialization will not use `BigDecimalSerializer` until `config.active_job.use_big_decimal_serializer` is enabled, which can be done safely after successful deployment of Rails 7.1. This option will be removed in Rails 7.2, when it will become the default. |
