Example RethinkDB Storage Setups
Example 1: A Partition of an AWS Instance Store
Many AWS EC2 instance types comes with an instance store: temporary storage that disappears when the instance disappears. (Some instance types don't come with an instance store, but you can attach EBS storage.) The size and setup of an instance store depends on the EC2 instance type.
We have some scripts for deploying a test BigchainDB cluster on AWS. Those scripts include commands to set up a partition (/dev/xvdb) on the instance store if that partition exists. Those commands can be found in the file /deploy-cluster-aws/fabfile.py, under def install_rethinkdb() (i.e. the function to install RethinkDB).
TODO: Discuss if/when one would use the instance store to store RethinkDB data.
Example 2: An Amazon EBS Volume
Amazon EBS volumes are always replicated.
Example 3: Using Amazon EFS
TODO
Example 4: A RAID Example?
Maybe make two EBS volumes look like one?
