How to define DLT table with cyclic reference

@Dlt.table
def table_A():
  return (
   dlt.read_stream(...)
  )

@dlt.table
def table_join_A_and_C():
  df_A = dlt.read_stream(table_A)
  df_C = dlt.read_stream(table_C)
  return (
   ....df_A.join(df_C)
  )

@dlt.table
def table_C():
  return (
   dlt.read_stream(table_join_A_and_C).....

  )

 

I got an error when defining DLT like above. Does DLT support cyclic reference?

Thanks in advance.
