____________ embodies the “share-nothing” architecture and essentially involves breaking a large database
into several smaller databases. Common ways to split a database include 1) splitting tables that are not joined
in the same query onto different hosts or 2) duplicating a table across multiple hosts and then using a hashing
algorithm to determine which host receives a given update.

Sharding embodies the “share-nothing” architecture and essentially just involves breaking a larger database up into smaller databases. Common ways to split a database are:
Splitting tables that are not joined in the same query onto different hosts
Duplicating a table across multiple hosts and then splitting where a row goes.
