The BP for the feature that added replica_count is here - <a href="https://github.com/openstack/trove-specs/blob/master/specs/kilo/replication-v2.rst">https://github.com/openstack/trove-specs/blob/master/specs/kilo/replication-v2.rst</a></div>

<div>Your suggestion for changing the semantic of the API is interesting – I would interested to know what others in the community thought about this as well. Maybe you could file a BP and suggest this improvement?</div>

<div>We have read the code of "replica_count" and it's like what I thought.</div>
<div><span style="line-height: 1.5;"><br>
</span></div>
<div><span style="line-height: 1.5;">We have an suggestion to extend this feature. When users set "slave_of_id" and "replica_count" at the same time, we just create replica instances. If they use "replica_count" without using "slave_of_id", we should create
an master instance for them and some replica instances of it.</span></div>
<div><span style="line-height: 1.5;"><br>
</span></div>
<div><span style="line-height: 1.5;">For example, "trove create $name --replica-of $id --replica_count=2" will create 2 replica instances. And "trove create $name --replica_count=2" will create 1 master instance and 2 replica instances.</span></div>

<div>Thanks Doug.</div>
<div>
<div> </div>
<div>It's really helpful and we need this feature as well. Can you point out the bp or patch of this?</div>
<div><br>
</div>
<div>I think we will add "--replica-count" parameter within trove create request. So trove-api will create trove instance(aync create nova instance) and then create some replica trove instances(aync create nova instances). This is really useful for web front-end
developers to create master and replica instances in the same time(they don't want to send multiple requests by themselves).</div>

<div>
<div>As of Kilo, you can add a —replica-count parameter to trove create —replica-of to have it spin up multiple mysql slaves simultaneously. This same construct is in the python/REST API as well. I realize that you still need to create a master first, but thought
I would point this out as it might be helpful to you.</div>

<div><br>
</div>
<div>
<div>
<div>Now we can create mysql master instance and slave instance one by one.</div>
<div><br>
</div>
<div>It would be much better to allow user to create one master instance and multiple slave instances with one request.</div>
<div><br>
</div>
<div>Any suggestion about this, the API design or the implementation?</div>
