Humio can provide auto-balanced partition table suggestions based on zones and replication factor settings. Suggestions will only be enabled when DIGEST_REPLICATION_FACTOR and STORAGE_REPLICATION_FACTOR settings are set. If no host has ZONE set, then each node is considered as being in its own zone. If ZONE is set, Humio will spread partitions across the different zones.

Zone label, eg. 'rack01' or 'rack02'. If not set, a node will be its own zone.

#ZONE=rack01
