Hi Raman, Sorry for the late reply but here it goes. So Gora is currently tied to Avro serialization thus you could start with Generic Avro Records, add properties, and schemas and whatever else you need at runtime. Then also you would need to convert those GenericRecords into Avro SpecificRecords that is what Gora uses [1] (btw you would have to make it extend from Gora PersistentBase) and then just use them. Of course this option might not be the fastest in terms of performance but you'd have to tried out and let us know ;) That would be a nice example to do/have though
