Alexander Liubushkin LLC "FORS Telecom"
Rustam AbdrakhimovThe talk covers the use of PostgreSQL, LUI and LUI4ORA2PG for building an analytical reporting system.
The talk tackles the following topics:
- migration from an Oracle environment;
- application of JSON functions;
- how the temporary tables helped us;
- our own means for load testing and bottlenecks detection;
- how to make beautiful GeoJSON format maps to display diagrams on them;
- installation and testing of the system on an "Elbrus" computer;
- what became an obstacle or was missing when using PostgreSQL.
The history of growth of the Live Universal Interface (LUI) web application development tool and the LUI4ORA2PG migration tool can be found in our previous presentations at PGConf conferences:

Pavel Tolmachev PostgresProThe more tables are involved with the query, the more difficult it is for the scheduler to choose a suitable execution plan (both time and memory usage increase). How can we "tell" the planner that it is better to connect this pair of tables first, and the rest can be connected later? What if we see that a part of our query can be improved, but the optimizer does not do this. In my presentation, I will talk about managing the order of connections. I will explain how we can influence the formation of a query plan using the standard "vanilla" PostgreSQL methods.

Дмитрий Головицин FORS Learning & Consulting CenterOur talk reviews the modern tools for administering PostgreSQL. It also covers the DBMS's performance bottlenecks and provides approaches to resolving the related issues. The presentation tackles the problems that occur while Oracle to Postgres migrations including the following: performance tuning tools (the analogues of AWR and ASH); monitoring tools (the analogues of Cloud Control); ensuring high availability and reliability of the database (grid infrastructure analogues); known "database performance bottlenecks"; an overview of options for technical support options SLAs.
