Atomic ( Slice key, Slice param, FdbMutationType type ) : void

Clear ( Slice key ) : void
ClearRange ( Slice beginKeyInclusive, Slice endKeyExclusive ) : void
CommitAsync ( CancellationToken cancellationToken ) : Task

Attempts to commit the sets and clears previously applied to the database snapshot represented by this transaction to the actual database. The commit may or may not succeed – in particular, if a conflicting transaction previously committed, then the commit must fail in order to preserve transactional isolation. If the commit does succeed, the transaction is durably committed to the database and all subsequently started transactions will observe its effects.

As with other client/server databases, in some failure scenarios a client may be unable to determine whether a transaction succeeded. In these cases, CommitAsync() will throw CommitUnknownResult error. The OnErrorAsync() function treats this error as retryable, so retry loops that don’t check for CommitUnknownResult could execute the transaction twice. In these cases, you must consider the idempotence of the transaction.
