Building real-time analytics with PostgreSQL
In today's world, operational reporting and real-time analytics are becoming a basic need. There are a huge number of tools, practices, and approaches, which in turn require different expertise and resources. In this talk, I will tell you how to transform your analytics using PostgreSQL. We'll discuss pitfalls when using different schemes. We'll talk about data quality and performance. I expect this talk to be of interest to both beginners and seasoned practitioners with many years of experience (Discussions and questions after the talk will be highly appreciated). The talk outline is as follows. 1. The evolution of reporting - migration from OLTP to OLAP. 2. Data delivery to DWH and related challenges. 3. Scaling architecture in response to growing data volumes. 4. Data quality issues. 5. Maintaining stability with a large number of changes. 6. Different approaches to organizing the work of the DWH team. 7. And, finally, we'll list the challenges we have successfully responded to with various solutions (pgAgent, PGWatch, working with the file system, the new reading of postgresql.conf).
