TiDB Operator 1.0.1 Release Notes

Release date: September 17, 2019

TiDB Operator version: 1.0.1

v1.0.1 What's New

Action Required

ACTION REQUIRED: We fixed a serious bug (#878) that could cause all PD and TiKV pods to be accidentally deleted when kube-apiserver fails. This would cause TiDB service outage. So if you are using v1.0.0 or prior versions, you must upgrade to v1.0.1.
ACTION REQUIRED: The backup tool image pingcap/tidb-cloud-backup uses a forked version of Mydumper. The current version pingcap/tidb-cloud-backup:20190610 contains a serious bug that could result in a missing column in the exported data. This is fixed in #29. And the default image used now contains this fixed version. So if you are using the old version image for backup, you must upgrade to use pingcap/tidb-cloud-backup:201908028 and do a new full backup to avoid potential data inconsistency.
