This complex advanced course, “ PostgreSQL Replication, High Availability HA and Scalability ” gives extensive knowledge about the scalability, replication, and high availability of PostgreSQL. The community of PostgreSQL is highly supportive and offers regular updates; this open-source, reliable, and user-friendly DBMS is the most preferred for many software systems. The issues directly arising from the need to construct large services that employ PostgreSQL consist of managing the availability of several servers and managing the various compromises of distributed systems.
In this course, “PostgreSQL Replication, High Availability HA and Scalability,” we review different architectures on how to scale reads and writes, replication and load balancing, connection pooling with queuing, partitioning and sharding, and the more recent multi-master solutions. Redundancy, available in various varieties, plays a significant role as a backup solution to the main server, which is likely to cause faults. Load balancing is very important for the load distribution in several database servers. We also discuss streaming and logical replication in depth, what you need to be aware of if you are using them, and the kinds of workloads they would be suitable for. PgBouncer is the connection pooler that is also analyzed, and recommendations on integrating it into a system to deal with many connections are provided.
Then, we delve into the practices of scaling PostgreSQL in the cloud, focusing on Google Cloud and basic components and configurations. There is partitioning for handling the big tables and sharding for introducing the scalability for writes at the cost of some challenges. We share step-by-step how-tos to create study high availability (HA) solutions in case of server failures with the help of log shipping, streaming replication, logical replication, cascading replication, and synchronous/asynchronous replication features. In the end, we talked about PgPool II and the settings for configuring it with streaming replication, load balancing, and high availability; we set up these and explained, but we also did all the configurations to engage the audience well. To the end of PostgreSQL Replication, High Availability HA and Scalability, you will gain all the necessary information to determine your scaled needs and apply the best solution for your case.
