Please describe what you are trying to understand

I've got an application using Persistence to SQL Server. I am attempting to project events into a more query-friendly SQL Server structure.

What did these pages not make clear?

On the Persistence Query page, the docs state:

Each read journal must explicitly document which types of queries it supports. Refer to your journal's plugins documentation for details on which queries and semantics it supports.

As far as I can tell, that means I should check this repo. However, this repo does not appear to say anything about the types of queries and semantics it supports, or any documentation of persistent views.

How can we do it better?

Usage documentation for this plugin around creating a persistent query or materialized view, perhaps with an example, would be phenomenal. I assume many like me may be encountering these topics for the first time and may require a little more hand-holding in terms of achieving an objective.
