Matt Pavlovich commented on AMQ-8593:
-------------------------------------

I think we should use "ha://". This transport is really just 'failover', but 
'failover' is already taken. We don't need to indicate anything about the 
architecture, b/c they are not related.

> Deprecate masterslave discovery agent and add a new leaderfollower discovery 
> agent

> raised the issue of non-inclusive terminology in the [AWS 
> docs|https://docs.aws.amazon.com/amazon-mq/latest/developer-guide/amazon-mq-creating-configuring-network-of-brokers.html#creating-configuring-network-of-brokers-configure-network-connectors]
>  and suggested that we should replace masterslave with an more inclusive name 
> for the network connector transport. The AWS docs refer to a feature of 
> ActiveMQ that is a convenience discovery agent: 
> [https://activemq.apache.org/networks-of-brokers#masterslave-discovery]
> Replacing master/slave nomenclature in ActiveMQ was raised in July 2020 
> AMQ-7514 and there have been some attempts at making some changes 
> ([#679|https://github.com/apache/activemq/pull/679], 
> [#714|https://github.com/apache/activemq/pull/714], 
> [#788|https://github.com/apache/activemq/pull/788]) however we have not been 
> able to come to an agreement on nomenclature so these efforts seem to have 
> stalled out.
> If we are able to come to an agreement on nomenclature in this PR, we can 
> move forward with removing more non-inclusive terminology on the website (I 
> will follow up with some PRs to the website), in discussions with the 
> community and of course in this codebase. This will remove adoption barriers 
> and make ActiveMQ a more approachable and inclusive project for everyone! 
> Other Apache projects such as Solr and Kafka have moved from master/slave to 
> leader/follower. Leader/follower is also recommended by the 
> [IETF|https://tools.ietf.org/id/draft-knodel-terminology-02.html] and 
> [inclusivenaming.org|https://inclusivenaming.org/word-lists/tier-1/] which is 
> supported by companies such as Cisco, Intel, and RedHat.
> If we can't come to an agreement on Leader/Follower or some other 
> nomenclature I will, at the very least, create a follow up PR to remove the 
> masterslave transport since it is just a convenience method to use 
> static+failover with ?randomize=false&maxReconnectAttempts=0.
> This change leaves the masterslave: transport in place but provides a new 
> alias leaderfollower: for now but we can easily remove it in 5.18.0.
