> We could use compression (e.g. snappy stream compression) to decrease the 
> size of our full checkpoints and savepoints. From some initial experiments, I 
> think there is great potential to achieve compression rates around 30-50%. 
> Given those numbers, I think this is very low hanging fruit to implement.
> One point to consider in the implementation is that compression blocks should 
> respect key-groups, i.e. typically it should make sense to compress per 
> key-group.
