What are the performance best practices for very large tables?
SOLUTION:
Here is a summary of best practices for querying, monitoring, and performance tuning for your very large tables:
- Pay attention to both the results of a query and the execution plan designed to return those results. Make it a routine exercise to scan query plans to become more familiar with how SQL Server resolves queries.
- De-normalize your schema where possible to reduce the need to join very large tables.
- Use table partitioning for your largest tables, and be sure when querying that the optimizer uses partition elimination whenever possible.
- Align secondary indexes with the same table partition function to reduce partitioned table maintenance.
- Consider using a heap instead of a clustered index, especially with a table that partially mimics a clustered index via its partition function.
- Design indexes to be covering for larger recurring queries whenever possible, especially when creating a filtered (i.e., partial) index.
- Use an indexed view as an alternative to a denormalized table or to materialize an aggregated dataset. The more static the underlying data, the less overhead will be required to maintain the indexed views.
- Use summary tables with automatic (scheduled) updates as an alternative to indexed views, especially when there is less significance in the currency of the data.
- For query monitoring, focus on the quantitative measures of Disk I/O, CPU Time, and Query Duration.
- Use the features of the Management Data Warehouse for overall server monitoring, and use the SQL Trace data collection set for query monitoring.
- Focus your tuning efforts on SQL code that is repeatedly run, either as a stored procedure or a SQL script, and that consumes the most server resources. Data warehouse applications tend to place the greatest pressure on Disk I/O.
- For tuning and management of large queries, consider saving historical copies of XML execution plans to disk for later reference.
