The Sliding Window Scenario

The sliding window scenario is a method for aging old data out and bringing new data into apartitioned table on a periodic basis. Using a time-based or date-based partitioned table, thetechnique employs the SWITCH option of ALTER TABLE, along with the MERGE and SPLIT

operations of ALTER PARTITION FUNCTION, to move the table's partitions forward in time onepartition at a time, leaving the overall number of partitions the same

The key feature of a sliding window scenario is that the partitions represent time linearly, andthe window of time slides forward period by period, keeping the overall number of partitions inthe partitioned table constant. The window moves forward partition by partition, reflecting theperiod of time chosen by the boundary values of the partition function.

Sliding Window Steps

In general, a sliding window consists of the following steps:

1. Create a nonpartitioned archive table with the same structure, and a matching clusteredindex (if required). Optionally you can add matching secondary indexes and constraints.

Place it on the same filegroup as the oldest partition.

2. Use SWITCH to move the oldest partition from the partitioned table to the archive table.

3. Remove the boundary value of the oldest partition using MERGE.

4. Designate the NEXT USED filegroup.

5. Create a new boundary value for the new partition using SPLIT (the best practice is tosplit an empty partition at the leading end of the table into two empty partitions tominimize data movement.).

6. Create a staging table that has the same structure as the partitioned table on the targetfilegroup.

7. Populate the staging table.

8. Add indexes.

9. Add a check constraint that matches the constraint of the new partition.

10. Ensure that all indexes are aligned.

11. Switch the newest data into the partitioned table (the staging table is now empty).

12. Update statistics on the partitioned table.

In addition, to protect the partitioned table from allowing any data values from beyond thedesired boundary range, a check constraint over the entire boundary range can be applied.

There are a number of things you can do to make the sliding window scenario as efficient aspossible:

Minimize data movement by using SPLIT and MERGE on empty partitions. Switching

out the oldest data partition and leaving an empty partition in its place allows you tomerge an empty partition. The same is true when you use the SPLIT operation to createthe partition for the newest data: It is initially an empty partition, so the SPLIT operation

does not cause any data movement.

Create the staging table for new data as initially a heap, load the data, and then buildindexes (and indexed views, if any) as a preparation for switching.

Update statistics on the table after every partition switching cycle (because statistics arekept at the table level, this operation can be time-consuming and resource intensive).


2/36

In a sliding window scenario, the oldest data switched out of the partition can be archived ordeleted, depending on business requirements. We'll deal with archiving scenarios in the nextsection.

Proposed Partition Schemes

The proposed partition schema is Horizontal Range Base Partition based on Index.

1. One Partition Function for Clustered Indexed Columns

2. One Partition Function for Non Clustered Indexed Columns (if Required).
