GKE tutorial: delete tidb cluster and pv before delete gke cluster #205

Deleting Kubernetes cluster would not delete the persistent disk volumes used by the cluster on GKE. So an extra step is needed in GKE tutorial to delete TiDB cluster cleanly before deleting Kubernetes cluster.

can you add the instruction? i am running load tests which require frequent clean up of old test data. is "truncate table" good enough?

tennix commented 5 years ago

Currently, you can follow the instructions here https://github.com/pingcap/tidb-operator/blob/master/docs/operation-guide.md#destroy-tidb-cluster I'll add these instructions to GKE tutorial later.

What did you mean by load tests? Is it functionality test or bench test? For bench test, you'd better create a new cluster each time because dropping database would require compaction in the background which impacts the performance. While for functionality test, it's ok to do so.
