Lightweight Transactions with DataStax Enterprise

Lightweight transactions enable highly durable distributed systems to operate in an ACID-like manner with ease. They ensure that data read is correct and current, which is crucial for maintaining data integrity. In DSE, lightweight transactions are implemented using the Paxos protocol combined with normal read/write operations. However, they have a relatively high cost of use and should only be utilized when necessary, such as in situations where concurrency is a factor. Consistency levels SERIAL and LOCAL_SERIAL are specific to lightweight transactions and provide linearizable consistency for handling failure scenarios.
