> Currently Sentry uses the "read-committed" consistency level which is the
> default for the Datanucleus JDO library. This causes potential problems since
> the state visible to each transaction can actually see updates from another
> transactions, so it is very difficult to reason about any code that reads
> multiple pieces of data.
> Instead it should use repeatable read" consistency which guarantees that any
> transaction only sees the state at the beginning of a transaction plus any
> updates done within a transaction.
