Here's how the use cas= e works: * My dataflow listens to Pubsub's subscription and gets the message in thi= s format :=C2=A0 {code:java} // {"schema" : , "payload" : ""} {code} * It then extracts the id, looks up schema registry and gets the schema fo= r a specific elelemt * The payload is then deserialised into GenericRecord * PCollection of these records is forwarded to BigQuery writer and it gets= written to BigQuery * It then is passed to Storage writer that writes to file system using Avr= oIO Now, I am struggling with the last step as AvroIO expects a schema whereas = I do not know schema at compile time. All I have is a bunch of elements wit= h schema id embedded. Is there any way for AvroIO to write the records to FileSystem without sche= ma? If not, do I have any other alternatives (formats) to write to file sys= tem? -- This message was sent by Atlassian JIRA (v7.6.3#76005)
