Hi Akram,
I hope this helps... let me know

When we put() [0] data in to Cassandra via Gora we first push into a
Collections.synchronizedMap(new LinkedHashMap<K, T>()) which acts as a
buffer for fields pending to be stored.
You can also refer to flush() method which itself calls addOrUpdate [1].
This is all Avro-based and hopefully there is something which will help you
out.
Lewis
