In the context of Delta Lake, explain how ACID transactions are implemented and what benefits they provide in a big data environment. Discuss specific scenarios where the lack of ACID compliance could lead to data integrity issues.
A
ACID transactions are implemented using a log file to record changes, providing scalability but not consistency.
B
ACID transactions ensure atomicity and isolation by using a commit log, but do not support durability.
C
ACID transactions in Delta Lake use a transaction log to ensure all operations are atomic, consistent, isolated, and durable, thus preventing data corruption and ensuring data integrity in concurrent operations.
D
ACID transactions are not supported in Delta Lake, leading to potential data inconsistencies.
