About This Course
This course is part of a series introducing solutions to running low-latency, highly resilient applications for data-intensive workloads on CockroachDB.
In this course we’ll focus on the question -- How do I survive large-scale infrastructure failures, like losing an entire cloud region, without losing data during recovery?
We’ll show you how to use CockroachDB Survival Goals in a multi-region cluster to implement a highly resilient database that survives node or network failures across multiple regions with zero data loss.
Suggested prerequisites
It would be helpful to be familiar with the following concepts:
- CockroachDB clusters, forming quorums and consensus
- Data distribution and replication in CockroachDB
- Cloud topology terms - Region & Availability Zone
A good prerequisite course for this is Intro to Distributed SQL and CockroachDB
