But with Delta Lake, ACID compliance is possible, and you can now leverage the features of ACID transactions that you used to get in Relational Database Management Systems (RDBMSes). Delta Lake uses optimistic concurrency control for handling transactions.

Optimistic concurrency control provides a mechanism to handle concurrent transactions that are changing data in the table. It ensures that all the transactions are completed successfully. A Delta Lake write operation is performed in three stages:
