The new partitioned table can be used for testing then dropped and created again with a different partitioning configuration to assist in finding the best partitioning strategy for your table and workload. Cons: Some downtime is required for the final data sync...
Details related to GUID partition table (GPT) disks are not addressed. However, disk partition alignment is a best practice, and it is required for optimal performance for each of these hard drive configurations: MBR basic MBR dynamic GPT basic ...
It is generally a good idea to map the measure group partitions to either separate SQL table partitions by using partition keys or onto a separate SQL table. Use partitioning wherever possible; this limits the amount of reprocessing that needs to be done based on your extraction, transformation,...
Use hash partitioning with a computed columnTable partitioning within SQL Server can be used to mitigate excessive latch contention. Creating a hash partitioning scheme with a computed column on a partitioned table is a common approach that can be accomplished with these steps:...
Best Practices: Partitioning Partition large fact tables Partitioning a table means splitting it horizontally into smaller components (calledpartitions). Partitioning brings several benefits. Essentially, partitioning enables the data to be segregated into sets. This alone has huge advantages in terms of ...
Bulk update (BU) locks allow multiple threads to bulk load data concurrently into the same table, while preventing other processes that aren't bulk loading data from accessing the table.The behavior is similar to when the user explicitly specifies TABLOCK hint while performing bulk load, or ...

NoSQL has document, graph, key-value, or wide-column store databases, while SQL has table-based databases. NoSQL is better suited for unstructured data, while SQL will likely use multi-row transactions. The bottom line Each database has its merits, but when considering SQL vs. NoSQL, it...
This way you will be able to run multiple versions of the same package, in parallel, that insert data into different partitions of the same table. When using partitioning, the SWITCH statement is your friend. It not only increases parallel load speeds, but also allows you to efficiently ...
