# Sentinel-managed Valkey for rspamd (bayes, history, ratelimit, gpt cache).
# rspamd has no Redis Cluster support, so the valkey-operator (cluster mode)
# cannot be used. start.sh follows the master the sentinels report; on a full
# restart the highest replication offset wins. Hostnames carry a trailing dot so
# lookups of a deleted pod fail fast instead of walking the search list (sentinel TILT).
