# Hazelcast Client Configuration for FT QoE Web
# =============================================================================
# This configuration connects FT QoE Web to the Hazelcast cluster for
# distributed caching and messaging. FT QoE Web reads the member list and the
# cluster name ONLY from this file -- HZ_MEMBERS in .env is not read.
