Generate hive types from Protocol buffers about hive

[incredimo]

hii.... just would like to know is such an adapter have been made... i find the perfomance of GRPC and Hive too good to keep them seperate. Thanks

My Use case is for CDC Architecture.

It works like this.

On Server you have a DB, It can be any DB.
When the data for a "View" changes you stream a CUD Event ( Create, Update, Delete) from the server to the Client ( Flutter ). Of course its only streamed to clients that have subscribed.

The CUD Event has:
a. a Change tpye ( Create, Update or Delete)
b. The data row.

These CUD events are modelled in your Server application tier as protobuf and so can be generated using hive generator. The use of protobufs ensures that everything is strongly typed but also that clients that have an old version do not break.

On the Client, the main Subscription handler receives all changes and then pushes them to the appropriate box ( one for each view) . The Hive watch then updates the graphical view.

Hope this helps.

For the transport i use Server Side events, rather than websockets, because of its better usage of battery and because subscriptions are one way. You dont need websockets bidirectional properties.
Also SSE is much easier to use in Flutter Web because its backed into Browsers.

You are correct, Hive type adapters are inspired by protobuf and work almost exactly the same.

Your approach sounds very interesting and I'd love to see if it actually works.

This is not something I want to implement for Hive itself but you could create a package. If you need any help / support just contact me.

yes its not something i expected to be put into this project.
I was wanting feedback about my presumptions, and it seems i was on the right track.

I will close this and get back to you if i get stuck.
