Provides a virtual resource that can be used to change advanced configuration options for a DigitalOcean managed MySQL database cluster.
-> Note MySQL configurations are only removed from state when destroyed. The remote configuration is not unset.
resource "digitalocean_database_mysql_config" "example" {
cluster_id = digitalocean_database_cluster.example.id
connect_timeout = 10
default_time_zone = "UTC"
}
resource "digitalocean_database_cluster" "example" {
name = "example-mysql-cluster"
engine = "mysql"
version = "8"
size = "db-s-1vcpu-1gb"
region = "nyc1"

}
The following arguments are supported. See the DigitalOcean API documentation for additional details on each option.
cluster_id

optimization. Default is 262144

- (Optional) Require primary key to be defined for new tables or old tables modified with ALTER TABLE and fail if missing. It is recommended to always have primary keys because various functionality may break if any large table is missing them.wait_timeout
- (Optional) The number of seconds the server waits for activity on a noninteractive connection before closing it.net_write_timeout
- (Optional) The number of seconds to wait for a block to be written to a connection before aborting the write.group_concat_max_len
- (Optional) The maximum permitted result length, in bytes, for the GROUP_CONCAT()

- (Optional) When enabled, records information about all deadlocks in InnoDB user transactions in the error log. Disabled by default.innodb_rollback_on_timeout
- (Optional) When enabled, transaction timeouts cause InnoDB to abort and roll back the entire transaction.internal_tmp_mem_storage_engine
- (Optional) The storage engine for in-memory internal temporary tables. Supported values are: TempTable
, MEMORY
.max_heap_table_size
- (Optional) The maximum size, in bytes, of internal in-memory tables. Also set tmp_table_size

seconds.backup_hour
- (Optional) The hour of day (in UTC) when backup for the service starts. New backup only starts if previous backup has already completed.backup_minute
- (Optional) The minute of the backup hour when backup for the service starts. New backup only starts if previous backup has already completed.binlog_retention_period
- (Optional) The minimum amount of time, in seconds, to keep binlog entries before deletion. This may be extended for services that require binlog entries for longer than the default, for example if using the MySQL Debezium Kafka connector.All above attributes are exported. If an attribute was set outside of Terraform, it will be computed.
A MySQL database cluster’s configuration can be imported using the id
the parent cluster, e.g.
terraform import digitalocean_database_mysql_config.example 4b62829a-9c42-465b-aaa3-84051048e712
