Description

Atlas server uses the value of property 'atlas.server.ha.enabled' to determine if Atlas is running in High-Available mode or not. Another property 'atlas.server.ids' lists all the server instances configured to run in the cluster. This and other related properties are used to determine if a server should be run in active or pass mode.

Instead of using 2 different properties, Atlas can determine if HA mode is enabled or not by looking at the number of instances listed in 'atlas.server.ids' property. When multiple instances are listed in this property, Atlas will run in HA mode; else it will run in stand-alone mode. Using a single property might be less confusing to manage and troubleshoot.
