Should you push or pull a spanner?
Always pull, rather than push, a wrench for greater control and balance. That way, if the nut or bolt should suddenly loosen, you're less likely to go flying. Never try to get more torque from a wrench by using a cheater bar or other device to extend the leverage.

How does Spanner provide high availability and scalability?
Each table in the database is stored sorted by primary key. Tables are divided by ranges of the primary key and these divisions are known as splits. Each split is managed completely independently by different Spanner nodes. The number of splits for a table varies according to the amount of data: empty tables have only a single split. The splits are rebalanced dynamically depending on the amount of data and the load (dynamic resharding). But remember that the table and nodes are replicated across three zones, how does that work?
How does Spanner provide global consistency?
TrueTime is essential to make Spanner work as well as it does...so, what is it, and how does it help?
How is split management replicated?
Everything is replicated across the three zones - the same goes for split management. Split replicas are associated with a group (Paxos) that spans zones. Using Paxos consensus protocols, one of the zones is determined to be a leader. The leader is responsible for managing write transactions for that split, while the other replicas can be used for reads. If a leader fails, the consensus is redetermined and a new leader may be chosen. For different splits, different zones can become leaders, thus distributing the leadership roles among all the Cloud Spanner compute nodes. Nodes will likely be both leaders for some splits and replicas for others. Using this distributed mechanism of splits, leaders, and replicas, Cloud Spanner achieves both high availability and scalability.
What is stale read?
Stale reads are used when low read latency is more important than getting the latest values, so some data staleness is tolerated . In a stale read, the client does not request the absolute latest version, just the data that is most recent (e.g. up to n seconds old). If the staleness factor is at least 15 seconds, the replica in most cases can simply return the data without even querying the leader as its internal state will show that the data is sufficiently up-to-date. You can see that in each of these read requests, no row locking was required - the ability for any node to respond to reads is what makes Cloud Spanner so fast and scalable.
What does replica request from leader?
The replica requests from the leader if it is OK to read and it asks for the TrueTime timestamp of the latest transaction on this row
