Evolution of Fault Tolerance in PostgreSQL: Synchronous Commit

Evolution of Fault Tolerance in PostgreSQL: Synchronous Commit

2ndQuadrant, Featured, Gulcin's PlanetPostgreSQL, PostgreSQL
PostgreSQL is an awesome project and it evolves at an amazing rate. We’ll focus on evolution of fault tolerance capabilities in PostgreSQL throughout its versions with a series of blog posts. This is the fourth post of the series and we’ll talk about synchronous commit and its effects on fault tolerance and dependability of PostgreSQL. If you would like to witness the evolution progress from the beginning, please check the first three blog posts of the series below. Each post is independent, so you don't actually need to read one to understand another.

This is the third post of the series and we’ll talk about timeline issues and their effects on fault tolerance and dependability of PostgreSQL. If you would like to witness the evolution progress from the beginning, please check the first two blog posts of the series: Evolution of Fault Tolerance in PostgreSQL  Evolution of Fault Tolerance in PostgreSQL: Replication Phase  Timelines The ability to restore the database to a previous point in time creates some complexities which we’ll cover some of the cases by explaining failover (Fig. 1), switchover (Fig. 2) and pg_rewind (Fig (more…)

Precisely one of the most gratifying results of intellectual evolution is the continuous opening up of new and greater prospects." Nikola Tesla PostgreSQL is an awesome project and it evolves at an amazing rate.
