Grigory Yaroslavtsev and collaborators present an improved approximation for the Directed Spanner Problem, exploring the concept of k-Spanner in directed graphs. The research delves into finding the sparsest k-spanner, preserving distances and discussing applications, including simulating synchroniz

Spanner, a strictly serializable system, leverages TrueTime for timestamping to enforce the invariant between transactions. It ensures efficient read-only transactions and multi-shard transactions. Mechanisms like 2PL, 2PC, and (Multi)Paxos contribute to Spanner's fault tolerance and scalability. Le
