 Druid uses the metadata store to house various metadata about the system, but not to store the actual data. The metadata store retains all metadata essential for a Druid cluster to work. **Apache Derby** is the default metadata store for Druid, however, it is not suitable for production. **MySQL** and **PostgreSQL** are more production suitable metadata stores.
 
-Luckily, **PostgreSQL** and **MySQL** both are readily available in KubeDB as CRD and KubeDB operator will automatically create a **MySQL** cluster and create a database in it named `druid` by default.

 Apache Druid uses [Apache ZooKeeper](https://zookeeper.apache.org/) (ZK) for management of current cluster state i.e. internal service discovery, coordination, and leader election.
 
-Fortunately, KubeDB also has support for **ZooKeeper** and can easily be deployed using the guide [here](/docs/guides/zookeeper/quickstart/quickstart.md)
