Ingesting data into Delta Lake using Mapping Data Flows

In the realm of data management, Atomicity, Consistency, Isolation, Durability (ACID) is a foundational set of principles ensuring the reliability and integrity of database transactions. Let’s break down the significance of each component:

  • Atomicity: Guarantees that a transaction is treated as a single, indivisible unit. It either executes in its entirety, or not at all. This ensures that even if a system failure occurs mid-transaction, the database remains in a consistent state.
  • Consistency: Enforces that a transaction brings the database from one valid state to another. Inconsistent states are avoided, providing a reliable and predictable environment for data operations.
  • Isolation: Ensures that transactions operate independently of each other, preventing interference. Isolation safeguards against concurrent transactions affecting each other’s outcomes, maintaining data integrity.
  • Durability...
