#
# == Class: tripleo::profile::base::database::mysql
#
# MySQL profile for tripleo
#
# === Parameters
#
# [*bind_address*]
# (Optional) The address that the local mysql instance should bind to.
# Defaults to $::hostname
#
# [*bootstrap_node*]
# (Optional) The hostname of the node responsible for bootstrapping tasks
# Defaults to hiera('mysql_short_bootstrap_node_name')
#
# [*certificate_specs*]
# (Optional) The specifications to give to certmonger for the certificate
# it will create. Note that the certificate nickname must be 'mysql' in
# the case of this service.
# Example with hiera:
# tripleo::profile::base::database::mysql::certificate_specs:
# hostname: <overcloud controller fqdn>
# service_certificate: <service certificate path>
# service_key: <service key path>
# principal: "mysql/<overcloud controller fqdn>"
# Defaults to {}.
#
# [*cipher_list*]
# (Optional) When enable_internal_tls is true, defines the list of allowed
# ciphers for the mysql server.
# Defaults to '!SSLv2:kEECDH:kRSA:kEDH:kPSK:+3DES:!aNULL:!eNULL:!MD5:!EXP:!RC4:!SEED:!IDEA:!DES:!SSLv3:!TLSv1'
#
# [*enable_internal_tls*]
# (Optional) Whether TLS in the internal network is enabled or not.
# Defaults to hiera('enable_internal_tls', false)
#
# [*generate_dropin_file_limit*]
# (Optional) Generate a systemd drop-in file to raise the file descriptor
# limit for the mysql service.
# Defaults to false
#
# [*innodb_buffer_pool_size*]
# (Optional) Configure the size of the MySQL buffer pool.
# Defaults to hiera('innodb_buffer_pool_size', undef)
#
# [*innodb_log_file_size*]
# (Optional) Configure the size in bytes of each log file in a log group.
# Defaults to undef.
#
# [*innodb_flush_method*]
# (Optional) Defines the method used to flush data to InnoDB data files and log files.
# Defaults to undef.
#
# [*innodb_lock_wait_timeout*]
# (Option) Time in seconds that an InnoDB transaction waits for an InnoDB row lock (not table lock).
# When this occurs, the statement (not transaction) is rolled back.
# Defaults to undef.
#
# [*table_open_cache*]
# (Optional) Configure the number of open tables for all threads.
# Increasing this value increases the number of file descriptors that mysqld requires.
# Defaults to undef.
#
# [*manage_resources*]
# (Optional) Whether or not manage root user, root my.cnf, and service.
# Defaults to true
#
# [*mysql_server_options*]
# (Optional) Extras options to deploy MySQL. Useful when deploying Galera cluster.
# Should be an hash.
# Defaults to {}
#
# [*mysql_max_connections*]
# (Optional) Maximum number of connections to MySQL.
# Defaults to hiera('mysql_max_connections', undef)
#
# [*remove_default_accounts*]
# (Optional) Whether or not remove default MySQL accounts.
# Defaults to true
#
# [*step*]
# (Optional) The current step in deployment. See tripleo-heat-templates
# for more details.
# Defaults to hiera('step')
#
