GaussDB(DWS) employs the shared-nothing architecture and the massively parallel processing (MPP) engine, and consists of numerous independent logical nodes that do not share the system resources such as CPUs, memory, and storage. In such a system architecture, service data is separately stored on...
The PostgreSQL server has a simple structure, consisting of a Shared Memory, Background Processes, and a Data Directory structure. In this section, we discuss each component, and how they interact with one another. Given below is an illustration of the PostgreSQL architecture. Initially, a reques...
This is the amount of memory that the database server uses for shared memory buffers. If this value is too low, the database would use more disk, which would cause more slowness, but if it is too high, could generate high memory utilization. According to the documentation, if you have ...

At some point, those modified in-memory pages are written to disk by the background writer. The important thing here is that data might be written out of order, which is no problem. Bear in mind that if a user wants to read data, PostgreSQL will check shared buffers before asking the ...
making them more structured. PostgreSQL version 15 will also save unusually slow checkpoint and autovacuum execution operations in logs by default. An interesting change may also be the storage of all server statistics in the server’s shared memory, making it possible to disable a separate statisti...
The simplest top-level way to think about the question: “which Postgres service on Azure is right for my application?” is this: Use Azure Database for PostgreSQL – Flexible Serverif you just need regular Postgres in the form of a managed service—with top of the li...
It is also critical to evaluate the cost of current security measures, their contribution to data security, and the expected return on investment from additional investments. Data Security vs Data Privacy Data privacy is the distinction between data in a computer system that can be shared with ...
