Optimizing Large Tables in SQL Server Using Table Partitioning
SQL Server table partitioning is an invaluable feature for improving database performance and management, especially for large-scale databases. This blog post provides an overview of setting up and managing partitioned tables in SQL Server, using TSQL commands. Partitioning helps manage large tables by dividing them into smaller, more manageable segments known as partitions. Each partition can be stored on a separate filegroup, enhancing query performance and simplifying maintenance tasks such as backups and index rebuilds.
Understanding Availability Group Synchronization in SQL Server
A fundamental aspect of managing Availability Groups is understanding how data synchronization occurs between the primary and secondary replicas within the group. This process ensures that all replicas are up-to-date, reflecting changes made in the primary database across all secondary databases in the group. Let’s look into how this synchronization works and the importance of the ‘redo’ operation in maintaining data consistency.
System Level Performance Tuning for SQL Server 2022 on Linux
Running SQL Server on Linux offers many advantages, including cost savings and robust management tools. To fully realize these benefits, certain Linux-specific configurations must be tuned. This post focuses on three specific areas: I/O scheduler, swapfiles, and swappiness. So let’s jump in and start tinkering!
Flow Control in Availability Groups and SQL Server 2022 Enhancements
SQL Server’s flow control in Availability Groups ensures optimal resource usage by managing log message distribution, thus safeguarding system performance. This mechanism operates seamlessly without compromising replica synchronization, with monitoring options available for detailed analysis.
