Enable Compression on a Table or Index.
More than one table or index can use the same partition function.
Enable Compression on a Table or Index.
Right-click the table or index to compress, point to Storage and select Manage Compression….
Lists each partition in the table or index.
A new table or index is generally allocated pages from mixed extents.
IAM(Index Allocation Map) contains information about extents used by a table or index.
Empty space can occur if each table or index record is more than half the size of a page, as then only a single record can be stored per-page.
The following example creates a partition function to partition a table or index into four partitions.
The table or index is treated as a single logical entity when queries or updates are performed on the data.
When the table or index grows to the point that it has eight pages, it then switches to use uniform extents for subsequent allocations.
Explains how to create partition functions and partition schemes, and how to apply them to a table or index.
To change the way a table or index is partitioned(from 10 partitions to 5, for example), you can use any one of the following options.
Runs DBCC CHECKTABLE on every table and view in the database- Checks the integrity of all the pages and structures that make up the table or indexed view.
A partition function defines how the rows of a table or index are mapped to a set of partitions based on the values of certain columns, called partitioning columns.
The query optimizer uses densities to enhance cardinality estimates for queries that return multiple columns from the same table or indexed view.
A database object that defines how the rows of a table or index are mapped to a set of partitions based on the values of certain column, called a partitioning column.
Index maintenance may increase the time that it takes to perform modifications, inserts, updates, or deletes, to the underlying table or indexed view.
Configuring a user database for full-text search involves creating one or more full-text catalogs for the database and defining a full-text index on each table or indexed view on which you want to execute full-text queries.
The SQL Server Query Optimizer relies on distribution statistics when it estimates the resource costs of different methods for extracting information from a table or index.
Statistics for query optimization are objects that contain statistical information about the distribution of values in one or more columns of a table or indexed view.
Partitioning large tables or indexes can have the following manageability and performance benefits.
These can either be base table or full index scans.
Allows users to access the underlying table or clustered index data and any associated nonclustered indexes during the index operation.
Allows users to access the underlying table or clustered index data and any associated nonclustered indexes during the index operation.
Performance gains are achieved because the query optimizer can locate all the column values within the index; table or clustered index data is not accessed resulting in fewer disk I/O operations.
