Uber engineers on the official blog have described why they switched from Postgres to MySQL database . Uber's early architecture was made up of back-end applications written by Python, using the Postgres database. Since then, Uber's architecture has changed dramatically, transforming to microservices models and new data platforms. Previously they used Postgres, a

Function Introduction POSTGRES-XC/XL/X2 is an open source project. It provides a multiple-master synchronous, transparent, PostgreSQL cluster solution. Unlike other cluster tools, it has a strong scalability when writing data, and introduces the concept of cluster environment with multiple master architectures. Multi-master means that when writing data, it is no longer subject to a single master node and will be well improved in writing speed.

process them separately according to the various commands of the client.The client initiates the request, and the PG server initiates a postgres access process for that request, which establishes a connection for that client through access. This postgres access process enters an infinite loop, waits for the client to request and pass the service for it until the process terminates, connecting the fracture.

Label:Recently the company requested to back up the database, so we looked up the comparative information. Don't say much nonsense, into the subject. Objective: To regularly back up the Postgres database under Ubuntu, and to pack and upload to the designated FTP server. After finding the information, the workaround: ① Write a backup database, package compression, upload the specified FTP script. ② adds the script to the Ubuntu scheduled Tasks crontab.

After postgres8.3, the default transitions between field data are canceled. If a data transformation is required, in the Postgres database, we can use "::" To convert the field data into a type. The actual "::" is called by the cast function. exactly what fields can be converted between data? This problem can be answered only by studying the cast function. The information of the cast function is managed in the System Pg_cast table. through the query
