(called a partitioning or just a partition) of shards whose ranges cover all possible keyspace ID values, while being non-overlapping and contiguous. Shards can be moved in and out of this list to determine following command (Ubuntu): ./kvtctld.sh Minikube Customizations The helm example is based on the values.yaml file provided as the default helm chart for Vitess. The following overrides have been performed recommended for a production environment. In such cases, you should start with the baseline values provided in helm/vitess/values.yaml and iterate from those. • etcd and VTGate replicas are set to 1. In a production

VIT-01-002 MySQL: Timing attacks due to plain-text password auth (Low) VIT-01-003 PII: Not all SQL values covered by SQL redaction (Low) Conclusions Introduction “Vitess is a database clustering system correctly sanitized, in particular due to the Angular framework’s proper handling of parameter-supplied values. Cure53, Berlin · 03/08/19 3/9 Dr.-Ing. Mario Heiderich redactor was checked for flaws allowing for the exfiltration of unredacted or incompletely redacted values. The minor issue was filed (see VIT-01-003) but the real-world impact, as with most information leak
