We are trying to convert hundreds of files (which are exports from DB tables) to avro.
The problem is that we dont want to enter the schemas manually, but read them from the DB (which we know how to of course).
How can we have some external schema file or dynamic update of the schema for tAvroOutput?
In talend, here is Dynamic schema feature which allows you to design schema with an unknown column structure (unknown name and number of columns).
Could you please take a look at this article about:How to process changing data structure?
