Query: Checking Robustness Against Snapshot Isolation   Transactional access to databases is an important abstraction allowing
programmers to consider blocks of actions (transactions) as executing in
isolation. The strongest consistency model is {\em serializability}, which
ensures the atomicity abstraction of transactions executing over a sequentially
consistent memory. Since ensuring serializability carries a significant penalty
on availability, modern databases provide weaker consistency models, one of the
most prominent being \emph{snapshot isolation}. In general, the correctness of
a program relying on serializable transactions may be broken when using weaker
models. However, certain programs may also be insensitive to consistency
relaxations, i.e., all their properties holding under serializability are
preserved even when they are executed over a weak consistent database and
without additional synchronization.
  In this paper, we address the issue of verifying if a given program is {\em
robust against snapshot isolation}, i.e., all its behaviors are serializable
even if it is executed over a database ensuring snapshot isolation. We show
that this verification problem is polynomial time reducible to a state
reachability problem in transactional programs over a sequentially consistent
shared memory. This reduction opens the door to the reuse of the classic
verification technology for reasoning about weakly-consistent programs. In
particular, we show that it can be used to derive a proof technique based on
Lipton's reduction theory that allows to prove programs robust.
