Read Skew

Read Skew is an example of a nonrepeatable read.

In the instance of a Read Skew, queries executed as part of a single transaction fetch data that is out of sync, because a transaction changed the data in the time gap between the queries.

Read Skew is a temporary problem, though. Refreshing the data (reloading the user interface, for example) will run the queries again, which will then correctly fetch the updated data.
