Defeat Page Latches by optimising for sequential key and other techniques in Microsoft SQL Server
Concurrent inserts into a clustered table with an ever-increasing key become a bottleneck since Microsoft SQL Server must protect the corresponding pages with a page latch. There are several techniques like, hash partitioning, reserve bits, in-memory OLTP and the feature introduced in 2019 CTP 3.1 called OPTIMIZE_FOR_SEQUENTIAL_KEY. We will compare these features to understand their performance improvements and the effort required to modify your existing application.

Hybrid Session
As well as getting back in person, we'll also have a Teams link available. Please answer the question when you register about whether you'll be there in person or remote. The Teams link will be provided closer to the event date.
What Else to Expect?
The chance to network. We plan to incorporate the best parts of SQL Social and the SQL Server Group in our new User Group, so there will be networking time, learning opportunities and introductions to new ideas.
Pizza and Door Prizes
Yes, we'd love to see you back in person if you are comfortable doing so. As a reward, we'll have pizza, maybe more muffins (they were great!) and door prizes for those who come along and join in the networking time.
