This chapter continues with a deeper dive on topology recommendations for different types of global sharding options depending on whether low latency or data control/sovereignty is the priority.
Key concepts
Before exploring some practical details about different global topologies, let’s review our understanding of sharding and zones in particular.
Chunks, splitting, and migration
As you will remember from Chapter 1, when sharding a collection, documents are broken into chunk ranges based on the shard key, and these chunks are distributed across the available shards. Chunks are normally ...
