Update or add a MemSQL database configuration as specified in the
memsql.cnf configuration file.
usage: memsql-ops memsql-update-config [--settings-file SETTINGS_FILE] [--async] [--all] [--no-prompt] --key KEY [--value [VALUE]] [--delete] [--set-global] [memsql_id] Change a config value for a MemSQL node. positional arguments: memsql_id The ID of the MemSQL node whose config you'd like to update. optional arguments: --settings-file SETTINGS_FILE A path to a MemSQL Ops settings.conf file. If not set, we will use the file in the same directory as the MemSQL Ops binary. --async If this option is true, we will exit without waiting for MemSQL to have its config changed. --all Update all MemSQL nodes' configs in the cluster. --no-prompt Skip interactive prompts if ID is not provided. This should be used for non-interactive scripts and automation. --key KEY The name of the config variable that you'd like to change. --value [VALUE] The value of the config variable that you'd like to set. If you pass in this option but do not give a value, we will set the config variable to an empty string. --delete If this value is passed in, we will delete the given variable from the config instead of setting its value. --set-global If this value is passed in, we will also attempt to run SET GLOBAL <key>=<value> on the MemSQL node, if it is running.
