So the cassandra map support in CQL is nice but it's got me wanting
deeper nesting.
For example { foo: { bar: hello } }
… but that's

Of course… one solution is something like avro, and then store your entire
record as a blob.
I guess that's not TOO bad but that means all
My personal opinion is that unless you are doing map operations on a CQL3 map
and will always intend to read the whole thing (you don’t have any choice
today), don’t use one at all - use a blob of whatever variety makes sense (e.g.
Json, AVRO, Protobuf etc)

We treat this on an Object level in Java as a new table with separate Hydration.
On a Map level we currently utilize an Internal CQL3 map where we replace the
non scalar values with
separate tables - we just stick the ID in.
Same for Sets, Arrays and such.
You get more writes but you also have

… but that's not possible with CQL
such as JSON or BSON in addition to the flattened leaf
values. Anything in your use case(s) that doesn’t cover?
