Yes, ConcurrentAppendException can be avoided if you are just accessing a table for reading purposes. This exception occurs when multiple processes try to insert data into the same table at the same time. As a reader, you are not modifying the table, so there is no chance of triggering this exception. However, if you are accessing a table that is being frequently modified by other processes, you may experience slower performance due to the high level of activity. In such cases, it is recommended to use a database that offers read replicas or sharding to distribute the load and improve performance.
