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, […]
Unlock the Power of Data Processing with Table-Valued Parameters in PostgreSQL Introduction: Table-valued parameters in PostgreSQL offer a convenient and efficient way to work with structured data. Instead of passing individual values as parameters, table-valued […]
