    GraphQL backend on PostgreSQL with plv8.

    Recently, I was working on a project where graphQL was used for sending requests to its .NET Core backend, but this was not a good idea. The point is, a graphQL query is a hierarchical structure with a dynamic set of fields. It’s difficult to perform such requests via a statically-typed programming language and a relational database as suggested by the tools available. So, I came up with the idea of using the plv8 extension and perform graphQL queries right on the database side. It took me about two hours to develop a working prototype that could perform the same queries as the software under development for more than one month! Then various improvements have been made and I want to introduce them all. If you are thinking of using graphQL instead of REST, my speech could be most useful and could help you to save a lot of time.

    Deploying a fault-tolerant PostgreSQL cluster on pacemaker

    Corosync & pacemaker is a well known solution for creating fault-tolerant clusters. Such clusters can contain 3 working nodes or 2 working nodes and one voting-only node. The cluster can be deployed on physical or virtual servers.

    This tutorial will demonstrate the process of installation and tuning of a PostgreSQL fault-tolerant cluster. You will learn that it is not so difficult as seems to be from the first glance.

    Real case of smooth MySQL → PG migration of highloaded project (20+M users)

    A brief story how MySQL → PG migration could increase company efficiency tenfold times:

    1. Program code has been reduced 50 times, with optimization of backend team (from 15 to 3 engineers)
    2. Software development of new features has become measuring in days, not in months
    3. Infrastructure costs per 1M users have been reduced 20 times
    4. Database structure and technical documentation were simplified significantly, from 100K high-dependent tables to just 20 simple tables
    5. New security level because of total forbidden on external SQL commands to the database
    6. Quick analytics aggregation on multiple parameters, without external analytics systems
    7. The last, but not the least: the main business was keeping alive during migration

    MobilityDB: Managing Mobility Data in PostgreSQL

    MobilityDB is an open source moving object database system (https://github.com/ULB-CoDE-WIT/MobilityDB). Its core function is to efficiently store and query mobility tracks, such as vehicle GPS trajectories. It implements the Moving Features specification from the Open Geospatial Consortium (OGC). MobiltyDB is engineered up from PostgreSQL and PostGIS, providing spatiotemporal data management via SQL. It thus integrates with the postgreSQL eco-system allowing for complex architectures such as mobility stream processing and cloud deployments.

    The presentation will explain the architecture of MobilityDB, its database types, indexes, and operations. We will highlight the PostgreSQL features that enable this extension, and the would like to have features. This presentation will be of special interest to the PostgreSQL community, and to professionals in the transportation domain.
