# Active/active eventual consistency (CRDT gossip). The server scales to any replica count
# via DNS peer discovery; independent managed clients scale alongside it and each fail over
# transparently. Dynamic Raft (strong) scaling is not supported here.
#
# Run from the repository root. Scale the servers, and with the clients profile the clients too:
#   docker compose -f samples/Redundancy/RedundantServer/Scale/docker-compose.yml up --build --scale server=5
#   docker compose -f samples/Redundancy/RedundantServer/Scale/docker-compose.yml --profile clients up --build --scale server=3 --scale client=2

  # Independent managed clients: each opts into WithServerRedundancy and fails over on its own,
  # so this scales to any count with --scale client=N (no shared client store needed). A
  # coordinated single-active client replica set instead uses AddRedundantClientSession + a
  # Raft client store (fixed quorum); see docs/HighAvailability.md. Part of the "clients"
  # profile so `up` without a profile runs the servers only.
