Are you sure Cassandra is a good fit for this kind of heavy update &
delete scenario ?

this sounds like relational thinking scenario... (no offense, I like
relational systems)
As if you want to maintain the state of a lot of entities with updates &
deletes, and you have a lot of state changes for your entities.
May be an eventstore/DDD approach would be a better model for that?
You could have an aggregate for each entity (ie. a record) you have in
your system and insert a new event record on each update of this agregate.
For example if you had to track the position of a lot of objects,
instead of updating the object records, each second you could insert a
new event with : (object: object_id, event_type: position_move, position
: x, y ).
Just a suggestion.
