Yuriy Plotnikov RTK IT LLC.We'll discuss our approaches to picking technical solutions for the systems we design. We'll consider their advantages and limitations. We'll share the facts about the changes in our engineering culture when import substitution requirements came into effect. We migrated the system with a classical three-tier architecture from Oracle to Postgres Pro DBMS. In my presentation I'll pay attention to data migration tools and peculiarities of development Java/Kotlin apps and SQL interoperability between two DBMSs.

We will also share our experience in time and resource savings, as well as data replication between our nodes. Performance test results will also be shared with the audience.

Andrey Borodin YandexFrom the very beginning of 2021, I'm fixing a bug in CREATE INDEX CONCURRENTLY. This bug manifests extremely seldom. I could not find any traces of it in mailing lists ever since the introduction of the feature in 8.2. Yet the bug affected our systems, so I decided to fix it. This is how the9i detective bug-hunting story started. In this story, I'll share details of the implementation of transactions and lock mechanics.
