More information about the course PostgreSQL High Performance Tuning Guide
PostgreSQL is one of the most powerful and easy-to-use database management systems. It has strong support from the community and is being actively developed with a new release every year. PostgreSQL supports the most advanced features included in SQL standards. It also provides NoSQL capabilities and very rich data types and extensions. All of this makes PostgreSQL a very attractive solution in software systems. However, getting the best performance from it has not been an easy subject to tackle. You need just the right combination of rules of thumb to get started, proper testing, solid monitoring, and maintenance to keep your system running well, and hints for add-on tools to add the features the core database doesn’t try to handle on its own. This Udemy course is structured to give you both the theoretical and practical aspects to implement a High-Performance Postgres. It will help you build dynamic database solutions for enterprise applications using one of the latest releases of PostgreSQL 12. You’ll examine all the advanced aspects of PostgreSQL 12 in detail, including logical replication, database clusters, performance tuning, and monitoring. You will also work with the PostgreSQL optimizer, configure Postgres for high speed by looking at transactions, locking, indexes, and optimizing queries. You are expected to have some exposure to databases. Basic familiarity with database objects such as tables and indexes is expected. You will find this Udemy course really useful if you have no or a little exposure to PostgreSQL. If you have been working with PostgreSQL for a few years, you should still find a few useful commands that you were not aware of or a couple of optimization approaches you have not tried. You will also gain more insight into how the database works. PostgreSQL Performance Tuning Online Course Curriculum: Understanding PostgreSQL Server Architecture In this section, we will explore the PostgreSQL Architecture. Shared Buffers works in cooperation with operating system cache, rather than replacing it. These caches improve performance by reducing the physical I/O necessary. Why we need to set Checkpoints carefully to limit crash recovery time, while not impacting the rest of the system’s performance. This section will give you all an introduction to why we need the WAL Writer and also the Background Writer. See the stages that the Query Processor has to pass in order to obtain the results. The utility Subsystem provides ways to maintain the database, such as claiming storage, updating statistics and logging. Configuring Vacuum for Performance We will understand why any time we do an UPDATE or DELETE, we will leave a dead row behind (and potentially a dead index entry) that needs to be cleaned up later by some form of vacuum. We will learn that when tables grow very large because of excessive dead tuples then performance will tend to decrease. Therefore the VACUUM process should never be avoided. This section explains why it’s better to have a steady low-intensity vacuum work , using the autovacuum feature of the database, instead of disabling that feature and having to do that cleanup in larger blocks. How to use an Index efficiently Understand that adding an index increase overhead every time you add or change rows in a table. Each index needs to satisfy enough queries to justify how much it costs to maintain. In this section, we’ll explain why the execution plan of a query depends on the data inside the table. If the data has low carnality , PostgreSQL will most probably ignore the index In this section we’ll learn why an index is only useful if it is selective ; it can be used to only return a small portion of the rows in a table. In this section, we will explore how to use bitmap scans effectively Index Optimization Tips On top of just using indexes, it is also possible to implement custom strategies for your particular application to speed things up How to be able to answer queries by only usi…
