# This is the config template for Citus Distributive Cluster
# tutorial: https://pigsty.io/docs/pgsql/kernel/citus
# we will use the local repo for cluster bootstrapping
#
# Topology:
# - pg-citus0: coordinator (10.10.10.10) VIP: 10.10.10.19
# - pg-citus1: worker group 1 (10.10.10.21, 22) VIP: 10.10.10.29
# - pg-citus2: worker group 2 (10.10.10.31, 32) VIP: 10.10.10.39
# - pg-citus3: worker group 3 (10.10.10.41, 42) VIP: 10.10.10.49
# - pg-citus4: worker group 4 (10.10.10.51, 52) VIP: 10.10.10.59
# - pg-citus5: worker group 5 (10.10.10.61, 62) VIP: 10.10.10.69
# - pg-citus6: worker group 6 (10.10.10.71, 72) VIP: 10.10.10.79
