Hello! I'm looking for any discussion or reference why the Schema object isn't serializable -- I'm pretty sure this must have already been discussed (but the keywords +avro +serializable +schema have MANY results in all the searches I did: JIRA, stack overflow, mailing list, web)
In particular, I was at a demo today where we were asked why Schemas needed to be passed as strings to run in distributed tasks. I remember running into this problem years ago with MapReduce, and again in Spark, and again in Beam... Is there any downside to making a Schema implement java.lang.Serializable? The only thing I can think of is that the schema _should not_ be serialized with the data, and making it non-serializable loosely enforces this (at the cost of continually writing different flavours of "Avro holders" for when you really do want to serialize it). Willing to create a JIRA and work on the implementation, of course! All my best, Ryan
