# Tablets

This simulation shows ScyllaDB **tablets**, the unit of data distribution that
replaces vnodes.

* Add, stop, decommission, and remove nodes.
* See the load balancer move tablet replicas until the load on each node and
  shard is equal again.
* Each balancing round uses the same rules as the ScyllaDB load balancer. The
  simulation shows the rule that stops each round.

#### NOTE
This is an educational simulation. It is simplified, and it does not show
all of the ScyllaDB internals exactly.
