2.2 TAO’s Goal
TAO provides basic access to the nodes and edges of a
constantly changing graph in data centers across multiple
regions. It is optimized heavily for reads, and explicitly
favors efficiency and availability over consistency.
A system like TAO is likely to be useful for any application
domain that needs to efficiently generate finegrained
customized content from highly interconnected
data. The application should not expect the data to be
stale in the common case, but should be able to tolerate
it. Many social networks fit in this category.
