very nice job.
About TDB concurrent transactions, do you mean nested transactions or
really concurrent transactions ?
Concurrent transactions are basically impossible with TDB, how would you
handle 2 separate transaction create an object with the same key ?
Concurrent transaction would be somewhat possible if we had a way to
restrict a transaction to act only on keys with a specific prefix,
maybe, but that seem a lot of work for little gain.
In what cases do you feel the need for concurrent transactions ?
