There are many reasons for partitioning your data and indexes in SQL Server, and one of them is because of the ease of moving data into and out of a table. The way SQL Server keeps track of the internal storage of partitioned data allows data movement to be done as a metadata only operation.
In this session we'll look at the metadata for table, index and partition storage to explore exactly what happens when a partition is moved. Looking at the internal details of partition storage allows us to understand the reasons for some of the restrictions on how and when we can get a benefit from partitioning.
In this session we'll look at:
How partitioning works
How your partitioned data is organized
The metadata behind your partitions
What is really happening when you switch partitions, split partitions and merge partitions
