I will try to figure out. Anyway, would this approach have a global impact, meaning only one type of schedule(s) will be applicable</div><div>for all the tenants or is there still some kind of flexibility for each tenant to apply own schedules in this way?

We currently deployed mysql,</div><div>mariadb and postgresql datastores with latest production-ready datastore versions for mysql and mariadb (5.7.34 and 10.4.18) and for postgresql it is version<br>12.4. </div><div><br></div><div>As You might understand, we have many questions unanswered, and if there is anyone capable and willing to answer some of them we would be very thankful:</div><div><br></div><div>- What is next in pipe in terms of production-ready datastore types and datastore versions?</div><div>- Clustering - according to the official documentation pages it is still experimental feature. When can we expect this to be supported and for what datastore types?</div><div>- According to some info we received earlier, PostgreSQL 12.4 is only partially supported - what part of functionality is not fully supported here - replication or something else?</div><div>- Creation of users and databases through OpenStack/Trove API is only supported with mysql datastore type. When can we expect the same level of functionality for at least the other two datastore types?</div><div>- MongoDB in particular, when can this datastore type be expected to be supported for deployment?</div><div>- In the case of database instance failure (for example failure due to the failure of the Compute node hosting the instance), is there any built-in mechanisms in Trove trying to<br> automatically bring up and recover the instance, that i am not aware of?</div><div><br></div><div>I am so sorry for this question bombarding but i simply have to ask :)</div><div><br></div><div>Thanks in advance!</div><div><br></div><div>Best regards</div><div class="iw-signature"><p><img class="fr-draggable" style="width: 1.7708in;
