Setting	Description
Member	`Ordinary member node`: A data-bearing member of the replica set that can become the primary and vote in elections.`Hidden node`: A data-bearing member of the replica set that can vote in elections. Corresponds to the `hidden` replica configuration option.`Hidden Delayed node` : A data-bearing member of the replica set that can vote in elections. Corresponds to the `secondaryDelaySecs` and `hidden` replica configuration options.
Hostname	Select from the menu the host to which Whaleal Automation deploys the replica set member. The menu only lists hosts under Whaleal Automation. This hostname can be a hostname or an IPv4 address.
Port	Specify the IANA port number for the `mongod` process. This setting corresponds to the `net.port` configuration file option. Defaults to `27017`.The `mongod` must have exclusive access to the specified port. If deploying multiple `mongod` processes to a single host, you must select a unique unused port for each process.
Votes	Specify the number of votes that the replica set member has during elections. This setting corresponds to the `votes` `mongod` replica set configuration option.
Priority	Specify the priority of the member during elections. Replica set members with a priority of `0` cannot become the primary and cannot trigger elections. This setting corresponds to the `priority` `mongod` replica set configuration option.
Delay	Specify the number of seconds "behind" the primary member this member should "lag". This setting corresponds to the `secondaryDelaySecs` `mongod` replica set configuration option.
Build Indexes	Specify `true` to direct the `mongod`] to build indexes. This setting corresponds to the `buildIndexes` `mongod` replica set configuration option. This setting corresponds to the `tags` `mongod` replica set configuration option.
