> ReadySet is a lightweight SQL caching engine that precomputes frequently-accessed query results and automatically keeps these results up-to-date over time as the underlying data in your database changes
Postgres materialized views have to be manually refreshed on a schedule, and so are always out of date, whereas ReadySet keeps your results up to date automatically as the input changes. For PG materialized views, the compute required proportional to the size of the input data, and is paid every time, whereas with ReadySet the computation is incremental, so it's proportional to the size of the change in the data over time.
And finally, ReadySet's (Noria's) big innovation is that the result set can be only partial, storing only the elements of the result set (and underlying data flow graph) that are frequently accessed, instead of the whole result set like a materialized view would.
Except then you need to be paying someone to monitor your queries and develop your views rather than just dropping a container in the middle with this app.
I don't see the point in using an extra app - you can do this natively in Postgres. Materialized views. https://www.postgresql.org/docs/current/rules-materializedvi...
