Baby-friendly Groups in Prague
Prague Playdates Meetup and more You have a little one who joined your family or joining soon and you don’t know how to find other parents like you, then online communities can come to your rescue. If you are an expat (or an English-speaking) parent in Prague, you can join the following groups I will mention in this post. I became a mother in June 2019.
Near-Zero Downtime Automated Upgrades of PostgreSQL Clusters in Cloud
I’ve started to write about the tool (pglupgrade) that I developed to perform near-zero downtime automated upgrades of PostgreSQL clusters. In this post, I’ll be talking about the tool and discuss its design details. You can check the first part of the series here: Near-Zero Downtime Automated Upgrades of PostgreSQL Clusters in Cloud (Part I). The tool is written in Ansible.
Near-Zero Downtime Automated Upgrades of PostgreSQL Clusters in Cloud
Last week, I was at Nordic PGDay 2018 and I had quite a few conversations about the tool that I wrote, namely pglupgrade, to automate PostgreSQL major version upgrades in a replication cluster setup. I was quite happy that it has been heard and some other people in different communities giving talks at meetups and other conferences about near-zero downtime upgrades using logical replication.
Prague PostgreSQL Meetup
Last month, I was at 2ndQuadrant booth at P2D2, an annual conference organized in Prague by local user group called CSPUG (Czech and Slovak PostgreSQL User Group). The conference was certainly a huge success and more than 200 people showed up! Meeting a lot of PostgreSQL enthusiasts in town, I wondered why there are no regular meetups in Prague.
Evolution of Fault Tolerance in PostgreSQL: Synchronous Commit
Synchronous replication guarantees that data is written to at least two nodes before the user or application is told that a transaction has committed. The user can select the commit mode of each transaction, so that it is possible to have both synchronous and asynchronous commit transactions running concurrently. This allows flexible trade-offs between performance and certainty of transaction durability.
Evolution of Fault Tolerance in PostgreSQL: Time Travel
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 third post of the series and we’ll talk about timeline issues and their effects on fault tolerance and dependability of PostgreSQL.
Evolution of Fault Tolerance in PostgreSQL
“It is paradoxical, yet true, to say, that the more we know, the more ignorant we become in the absolute sense, for it is only through enlightenment that we become conscious of our limitations. 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.
Evolution of Fault Tolerance in PostgreSQL: Replication Phase
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 second post of the series and we’ll talk about replication and its importance on fault tolerance and dependability of PostgreSQL.
Are we ready for Nordic PGDay?
The 3rd annual Nordic PGDay will be held on 17th of March in Helsinki this year. Registration is still open, reserve yourselves a seat before it’s too late! Nordic PGDay is visiting a different Nordic city each year as a tradition.
FLOSS UK Spring Conference
Floss UK Spring conference will be held on 15th-17th of March in London. FLOSS UK is the name for UK’s oldest open systems user group. On their website they define themselves like below: FLOSS UK is for people who care about open IT standards and the systems that implement them. We therefore promote the use of open standards across all technological fields. We encompass hardware, software, data and connected disciplines; our favourite tag line is ‘free and open technology’.
Prague PostgreSQL Developer Day 2016
The 9th annual “Prague PostgreSQL Developer Day” conference will be held on 17th and 18th February in Prague. Me with PostgreSQL elephants at Prague Zoo :) Prague PostgreSQL Developer Day is a two day conference and talks & trainings are mostly in Czech language. Conference program is also ready, you can check the full schedule. The first day of the conference, there will be trainings and practical lectures for a smaller number of attendees. You can find the detailed trainings program.
Tablesample and Other Methods for Getting Random Tuples
PostgreSQL’s TABLESAMPLE brings a few more advantages compared to other traditional ways for getting random tuples. TABLESAMPLE is a SQL SELECT clause and it provides two sampling methods which are SYSTEM and BERNOULLI. With the help of TABLESAMPLE we can easily retrieve random rows from a table. For further reading about TABLESAMPLE you can check the previous blog post. In this blog post we’ll talk about alternative ways of getting random rows.
