TimescaleDB extension allows to turn good old Postgres into a real distributed cluster for storing time series data while maintaining the relational model, convenient SQL and a time-tested ecosystem. And additional features such as continuous materialized views and data compression allow to build truly powerful telematic hubs.

What can be more important in the data load process than speed? Data migration is one of the most requested features in DBeaver. So the performance issue was highly important for us, in regard to PostgreSQL, as well as Greenplum, Redshift and other Postgres-based databases. We are ready to share our tiny secrets about 10x, 100x, 1000x, and even 10,000x performance improvements for data imports without any magic.

The pgpro_scheduler extension has an interesting but little-known feature - one-time jobs. Despite its simplicity, this feature can be used for complex transaction processing. On the one hand, it helps to reliably execute tasks taking a very long time, on the other hand, it ensures app scaling if certain conditions are met.
