Process Memory Protection in PostgreSQL Process memory protection in PostgreSQL is primarily implemented through the use of memory management techniques provided by the operating system. PostgreSQL relies on the underlying operating system’s memory management capabilities […]
PostgreSQL‘s cost-based optimizer (CBO) is responsible for determining the most efficient execution plan for a given query. To influence the CBO and improve performance, you can follow these tips: By following these tips, you can influence […]
Data structures play a critical role in defining the efficiency and effectiveness of a database management system (DBMS). InnoDB, the default storage engine for MySQL, relies heavily on two types of data structures – B+Trees and […]
In the realm of MySQL database engines, InnoDB stands out as a powerful and widely used engine. It is renowned for its robustness, reliability, and performance. However, like all software, it is not exempt from […]
Introduction: In the world of relational databases, PostgreSQL stands out as a robust and feature-rich option. Among its many powerful capabilities is the Multi-Version Concurrency Control (MVCC) system. While MVCC is an essential aspect of […]
PostgreSQL Locking Managing locking in PostgreSQL is crucial for improving concurrency and ensuring efficient data access in a multi-user environment. To achieve this, follow these best practices: Use Row-level Locking PostgreSQL offers different locking modes. […]
PostgreSQL Waits In PostgreSQL, backup-related waits occur when performing database backups with tools like pg_dump or pg_basebackup. These waits usually stem from I/O operations since the process involves reading data from disk and writing it […]
Here are some tips and tricks to troubleshoot indexes with high maintenance costs in PostgreSQL: Remember to thoroughly test any changes you make and monitor the impact on both query performance and maintenance costs.
The wait/synch/mutex/sql/MYSQL_BIN_LOG::LOCK_commit and wait/synch/mutex/sql/MYSQL_BIN_LOG::LOCK_commit_queue mutexes in MySQL can have significant implications on database performance. In summary, high contention for these mutexes can be indicative of performance issues in MySQL, including I/O bottlenecks and inefficiencies in transaction […]
Introduction Configuring Linux threads for optimal system performance requires several strategies and considerations. Adjusting thread scheduling policies, priorities, CPU affinity, and other parameters fine-tunes thread behavior to maximize performance. Additionally, techniques such as thread pooling, […]
