+
+# mysql\_ti\_config
+
+The ``mysql_ti_config`` resource manages a TiKV or PD variables on a TiDB cluster.
+
+~> **Note on TiDB:** Possible TiKV or PD variables are available [here](https://docs.pingcap.com/tidb/stable/dynamic-config)
+
+~> **Note about `destroy`:** `destroy` is trying restore default values as described [here](https://github.com/petoju/terraform-provider-mysql/blob/master/mysql/resource_ti_config_defaults.go).
+  Unfortunately not every variable support this.
+
+## Example Usage
+
+### PD
+
+```hcl
+resource "mysql_ti_config" "log_level" {
+  name = "log.level"
+  value = "warn"
+  type = "pd"
+}
+```
+
+#### Set variable for all PD instances
+
+```hcl
+resource "mysql_ti_config" "log_level" {
+  name = "log.level"
+  value = "warn"
+  type = "pd"
+}
+```
+
+#### Set variable for one PD instance only
+
+```hcl
+resource "mysql_ti_config" "log_level" {
+  name = "log.level"
+  value = "warn"
+  type = "pd"
+  instance = "127.0.0.1:2379"
+}
+```
+
+## TiKV
+
+### Set varibale for all TiKV instances
+
+```hcl
+resource "mysql_ti_config" "split_qps_threshold" {
+  name = "split.qps-threshold"
+  value = "100"
+  type = "tikv"
+}
+```
+
+#### Set variable for one TiKV instance only
+
+```hcl
+resource "mysql_ti_config" "split_qps_threshold" {
+  name = "split.qps-threshold"
+  value = "10"
+  type = "tikv"
+  instance = "127.0.0.1:20180"
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `name` - (Required) The name of the configuration variable.
+* `value` - (Required) The value of the configuration variable as string.
+* `type` - (Required) The instance type to configure. Possible values are tikv or pd.
+
+## Attributes Reference
+
+No further attributes are exported.
+
+## Import
+
+TiKV or PD variable can be imported using global variable name.
+
+General template to import is
+
+```terraform import mysql_ti_config.<tf_name> <pd|tikv#config#optional_instance_name>```
+```terraform import mysql_ti_config.<tf_config_name_in_tf_file> <pd|tikv#config_param_to_read#optional_instance_name>```
+
+### Simple example
+
+#### TiKV example
+
+```shell
+terraform import 'mysql_ti_config.split_qps_threshold' 'tikv#split-qps-threshold'
+```
+
+Import value for specific instance
+
+```shell
+terraform import 'mysql_ti_config.split_qps_threshold' 'tikv#split-qps-threshold#127.0.0.1:20180'
+```
+
+#### PD example
+
+```shell
+terraform import 'mysql_ti_config.log_level' 'pd#log.level'
+```
