NoSQL databases do not support ACID transactions at all.

  1. True
  2. False

Answer: False

Many modern NoSQL databases support ACID transactions, at least for single-document or single-partition operations. Examples: MongoDB (multi-document ACID since 4.0), Cassandra (lightweight transactions), Google Spanner (globally distributed ACID). Trade-offs exist between consistency, availability, and partition tolerance (CAP theorem).
