thinking through: persistence if keyspace is dropped before opened partitions

[cablehead]

I'm not sure what the right thing to do is. Perhaps just document: "you'll want to keep a reference to your keyspace, while you still have an open partition", or make it not allowed to keep a reference to a partition, after the keyspace has been dropped?

Yeah I am not sure how to handle it nicely. I don't think giving PartitionHandle is that ergonomic, and just handing out short-lived handles is not feasible because that just makes every operation go through another RwLock, which I want to avoid.

The only thing I can think of is to keep track of open partitions in a separate RC-ed structure that references the keyspace, so that when the keyspace is dropped, it is still referenced. Then when all partitions are dropped at last, the RC drops to 0, the struct is dropped and thus the keyspace, too...

Perhaps just document: "you'll want to keep a reference to your keyspace, while you still have an open partition"

It should definitely be documented that the keyspace should ideally be kept around for the entire duration of the program, or at least as long as partitions are open...
