Demo of CockroachDB's self-healing capabilities

This demo will show you the self-healing capabilities of CockroachDB. In scenarios where your number of nodes is larger than your configured replication factor (assuming constraints like replication zones are met) CockroachDB will automatically up-replicate data of a failed node onto the remaining ones, in order to restore the desired

availability

Demo of CockroachDB's in-place rolling upgrades

In this demo I'm going to walk you through how an in-place rolling-upgrade works with CockroachDB and that it can be performed without any type of downtime. I've chosen to walk you through the "manual" approach, to be able to explain whats happening under the covers. Under normal circumstances you

always on

Demo of CockroachDB surviving a regional outage

In this demo I'll show you one of the key characteristics of CockroachDB, its multi-regional survivability. CockroachDB clusters can easily spanning multiple geographic regions and replicate your data across those regions for maximum availability, in order to help you design systems with "always-on" requirements, which will help to drive negative
