Yes idea was to have the compose_id as a document root since it is unique
for each compose.
something like this:

Fedora-Rawhide-20230913.n.0:{
compose_related_metadata:[metadata0:metadata,metadata1:metadata]
rpms:[nvr:other_rdata,nvr1:other_rdata1]
images:{Fedora-Sway-Live-x86_64-Rawhide-20230913.n.0.iso:"some metadata"}
}

If we store the data in the correct format for fedfind use case we can
minimize the number of operations that are needed compared to REST API.

I will start working on this on the 15th. My idea is to start with the data
format, Once that is sorted out.

Just a friendly reminder we will not drop PDC suddenly. The plan is to
implement the new solution and have it running in parallel with PDC for a
while,
Once we are sure everything is working we will start to sunset PDC.
