In most cases, you would just need to setup one filer store.
However, there are some examples that one filer store is not enough:
* The filer store that is not linearly scalable.
* A portion of the data is critical and needs Etcd for strong consistency but acceptable low performance.
* A portion of the data is critical and needs strong consistency and is ok with high latency.
* With too many updates in a directory, the Cassandra with LSM tree becomes slower with too many tombstones. You may want to use Redis for that directory.
* One filer store can not handle the amount of files. We can add more file stores for big directories to ensure linear scalability.
* One directory operations are hot. Having a separate store can physically isolate from and avoid impact to other directories.
