In this blog post, we will continue to explore Vitess and test an example database provided in its repository. This is Part III of the previously discussed installation of Vitess on minikube environment, so please make sure to follow those steps to bring the cluster up to the following level.

Creating a Keyspace
The sample helm chart provides single unsharded keyspace with a single shard named 0:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 |
mysql> show databases; +-----------+ | Databases | +-----------+ | commerce | +-----------+ 1 row in set (0.00 sec) mysql> show tables; +--------------------+ | Tables_in_commerce | +--------------------+ | corder | | customer | | product | +--------------------+ 3 rows in set (0.01 sec) |
The sample schema is simple enough to have only fields required to demonstrate sharding scheme.
