Joshua D. Drake Postgres Performance and Maintenance

presented by Joshua D. Drake

When you are optimizing PostgreSQL it is usually maintenance that goes by the wayside. How do we fix autovacuum? Where did all of this bloat come from? Why am I getting IO spikes? How do I get RDS to behave?! Why are commits so slow on replication? The answer to all of these questions is understanding the relationship between proper Postgres maintenance and performance. Join us for a 3 hour jau...

QUAN-HA LE Mainur Rahman Semantic Search Web System on PostgreSQL
PostgreSQL Semantic Search

presented by QUAN-HA LE and Mainur Rahman

Web search engines often federate many user queries to relevant structured databases. For example, a recruitment-related query might be federated to a jobseekers-and-employers database containing their resumes and skills. The relevant structured data items are then returned to the user along with web search results. Though each structured database is searched in isolation, the search often prod...

Mike Freedman Building a scalable time-series database on PostgreSQL
TimescaleDB, packaged as a PostgresSQL extension

presented by Mike Freedman

Today everything is instrumented, generating more and more time-series data streams that need to be monitored and analyzed. When it comes to storing this data, many developers often start with some well-trusted system like PostgreSQL, but when their data hits a certain scale, give up its query power and ecosystem by migrating to some NoSQL or other "modern" time-series architecture. They face t...
