Cassandra error handling done right

Proper error handling in Cassandra is crucial to ensure data safety and continuous availability of clusters. Understanding the various types of exceptions thrown by drivers can help developers handle errors effectively. Some common exceptions include NoHostAvailableException, UnavailableException, ReadTimeoutException, WriteTimeoutException, QueryValidationException, and others. Handling these exceptions properly involves understanding their causes and implementing appropriate retry policies. Using idempotent operations, such as CAS (Compare-And-Set) operations, can also help manage errors in Cassandra. Additionally, developers should be cautious when using non-idempotent operations like counter updates or list append/prepend operations, as they may lead to data inconsistencies.
