# High Availability Tempo Configuration for docker-compose-example-for-rustfs.yml
# Features:
# - Distributed architecture with multiple components
# - Kafka-based ingestion for fault tolerance
# - Replication factor of 3 for data resilience
# - Query frontend for load balancing
# - Metrics generation from traces
# - WAL for durability
