- is there a thread-safe version of HTree.keys or HTree.values that
would allow me to add/remove entries in another thread whilst I am
iterating all the keys/values? Or is this the kind of operation that
one must obtain a lock for?
- there doesn't seem to be a way to explicitly start a transaction,
just commit one. Is the start of a transaction determined from certain
actions (e.g. an HTree.put or remove)? If so... is a transaction
limited to a single thread?
- what happens if 2 threads put different entries (with different
keys) into a HTree at the same time... these are non-conflicting
transactions so I would not expect there to be a problem. Should I
ever expect an exception in that situation? Not knowing where the
transaction begins, it might be the case that the last committer wins.
