  • Ask HN: Is there a way to subscribe to an SQL query for changes?

    I know [RethinkDB][1] used to do this with their SQL-like ReQL language, but I looked around a bit and can't find much else about it - and I would have thought it would be more common.

    If we think about modern frontends using SQL-based backends, essentially every time we render, its ultimately the result of a tree of SQL queries (queries depend on results of other queries) running in the backend. Our frontend app state is just a tree of materialized views of our database which depend on each other. We've got a bunch of state management libraries that deal with trees but they don't fit so well with relational/graph-like data.

    I came across a Postgres proposal for [Incremental View Maintenance][2] which generates a diff against an existing query with the purpose of updating a materialized view. Oracle also has [`FAST REFRESH`](https://docs.oracle.com/database/121/DWHSG/refresh.htm#DWHSG8361) for materialized views.

    I guess it's relatively easy to do until you start needing joins or traversing graphs/hierarchies - which is why its maybe avoided.
