How we said goodbye to MongoDB and switched to PostgreSQL

In this talk I will share the experience of migration, NoSQL data to a relational view convert, and tell you how we managed to speed up the application in 2 times.

Initially, we used PosgtgreSQL and MongoDB to store all the data. In practice, we found out that the separation is extremely inconvenient. We spent a lot of time and attention on it.

My talk will describe how we moved the data from MongoDB to PostgreSQL using mosql. As a result, all the data can be received by one query now, and the table schema ensures data consistency.

Distributed Point-In-Time Recovery with Postgres

Postgres has a nice feature called Point-in-time Recovery (PITR) that would allow you to go back in time. In this talk, we will discuss what are the use-cases of PITR, how to prepare your database for PITR by setting good base backup and WAL shipping setups, with some examples. We will expand the discussion with how to achieve PITR if you have a distributed and sharded Postgres setup by mentioning challenges such as clock differences and ways to overcome them, such as two-phase commit and pg_create_restore_point.

Tutorial: Management of High-Availability PostgreSQL clusters with Patroni

Patroni is a Python application to create high-availability PostgreSQL clusters based on the streaming replication. It is used by Red Hat, IBM Compose, Zalando and many other companies. This tutorial will highlight Patroni architecture, provide attendees with hands-on experience of configuring high-availability PostgreSQL clusters with Patroni, describe how to take advantage of numerous additional features and give an opportunity to learn more about common mistakes related to running Patroni and its troubleshooting.

In order to take most out of the Patroni tutorial one needs a laptop with git, vagrant and virtual box installed.
Vagrant can be obtained from https://www.vagrantup.com Virtualbox is at https://www.vagrantup.com
Alternatively, one can install your Linux distribution packages (or use homebrew on Mac).
Once Vagrant and Virtualbox are installed one can run the Patroni VM by issuing the following commands:
```
$ git clone https://github.com/alexeyklyukin/patroni-training
$ cd patroni-training
$ vagrant up
```
When the setup concludes Patroni box can be accessed via ssh using vagrant ssh command.
