Let Me Finish…
Isolating Write Operations OLTP databases can be constantly written to and reporting databases are written to at least periodically. In order to ensure consistent results, connections must be isolated from one another while executing, ideally with the lowest possible cost to concurrency. How this isolation is handled is based on the isolation level, whether the classic lock based or the newer optimistic scheme of the in-memory OLTP engine is used, or even if both engines are enlisted in the same transaction. In this session we will look at examples of how SQL Server isolates reading and writing operations from other writing operations to explore how this may affect your application through error messages and performance hits.
