| | | | | Spanner is a rare example of a distributed database that supports externally consistent distributed transactions. Many other databases either choose not to implement distributed transactions at all, or opt for weaker consistency models because of the performance cost involved. In this post, we'll learn how Google's TrueTime API enables it to provide this guarantee at a good performance. | |

| | | | | In the previous blog post, we saw how a transaction isolation strategy built on multi-version concurrency control (MVCC) does not implement the serializable isolation level. Instead, it implements a weaker isolation level called snapshot isolation. In this post, I'll discuss how that MVCC model can be extended in order to achieve serializability, based on work... | |

| | | Vast of the today's applications leverage on some type of a database that provides ACID guarantees with transactions. It is important to know the differences between different isolation levels to facilitate the choice when applying them... | ||
