In the video, I delved into the concepts of CAP theorem and its practical implications using examples from Google's Spanner database blog. CAP theorem, introduced by Eric Brewer, states that distributed data stores can provide only two out of three guarantees: Consistency, Availability, and Partition Tolerance. I explained the differences between consistency in ACID and CAP theorem, highlighting the trade-offs between consistency and availability during network partitions. Google Spanner aims to achieve both consistency and availability through globally distributed data management and specialized hardware like the TrueTime algorithm, challenging traditional CAP theorem assumptions.
