Supporting multi-active replication with geosharding in PostgreSQL
Talk by Denis Lussier
https://www.socallinuxexpo.org/scale/...
We will discuss the work we've done to bring back multi-active logical replication (MMR) in a new derivative of pgLogical. We'll also cover how we implement geosharding in support of low latency, cross-region scale-out and data residency use cases. For the latter we'll focus on enhancements we've made to ensure PII doesn't cross national or regional borders. Finally we'll show a demonstration of multi-active bidirectional replication across 3 continents and 2 clouds, showcasing low latency for database users across multiple geographies.
