# Pyroscope v2 components

Pyroscope v2 includes a set of components that interact to form a cluster.

Most components are stateless and don’t require any data persisted between process restarts. The [metastore](metastore/) is the only stateful component in the architecture, using Raft consensus for replication and fault tolerance.
