The question was do heaps are very bad and always force a table scan? Let us learn about RID Lookup, Heaps and table scan.
Every consulting engagement is different and I enjoy interacting with different people while I am working with different experts. Earlier this week, here is what I heard during one of the Comprehensive Database Performance Health Check engagement about Parallelism for Heap Scan.
During the early year of my career, one of the most popular questions I used to receive was – What is Forwarded Record? I used to find this question very valid as many people yet did not know what is the forwarded record. In most of the cases as time passes by more knowledge is spread amount SQL Server users and the number of questions reduces on a single topic. However, this is something I can’t say is true for Forwarded Records.
