Constants

const DefaultConfigLocation = "/etc/clickhouse-server/"

const ProcessedConfigurationLocation = "/var/lib/clickhouse/preprocessed_configs"

const SystemDatabase = "system"

Variables

var BannedTables = []string{"numbers", "zeros"}

BannedTables - Hardcoded list. These are always excluded even if the user doesn't specify in exclude_tables. Attempts to export will work but we will warn

var DbLogTables = map[string]DBLogTable{
	"query_log": {
		// contains filtered or unexported fields
	},
	"query_thread_log": {
		// contains filtered or unexported fields
	},
	"text_log": {
		// contains filtered or unexported fields
	},
}

var DefaultLogsLocation = filepath.Clean("/var/log/clickhouse-server/")

var ExcludeColumns = map[string][]string{}

ExcludeColumns columns if we need - this will be refined over time [table_name][columnA, columnB]

var OrderBy = map[string]data.OrderBy{
	"errors": {
		Column: "last_error_message",
		Order:  data.Desc,
	},
	"replication_queue": {
		Column: "create_time",
		Order:  data.Asc,
	},
}

OrderBy contains a map of tables to an order by clause - by default we don't order table dumps
