!CHAPTER Scalability
|
|
|
|
ArangoDB is a distributed database supporting multiple data models,
|
|
and can thus be scaled horizontally, that is, by using many servers,
|
|
typically based on commodity hardware. This approach not only delivers
|
|
performance as well as capacity improvements, but also achieves
|
|
resilience by means of replication and automatic failover. Furthermore,
|
|
one can build systems that scale their capacity dynamically up and down
|
|
automatically according to demand.
|
|
|
|
Obviously, one can also scale ArangoDB vertically, that is, by using
|
|
ever larger servers. However, this has the disadvantage that the
|
|
costs grow faster than linear with the size of the server, and
|
|
none of the resilience and dynamical capabilities can be achieved
|
|
in this way.
|
|
|
|
In this chapter we explain the distributed architecture of ArangoDB and
|
|
discuss its scalability features and limitations:
