A comma-separated list of column names or aliases that determines the sort order. Sorting defaults to ascending and can be changed by setting :asc or :desc as a suffix to the column name.

The period to wait for a connection to the master node.

Specifies the format to return the columnar data in, can be set to text, json, cbor, yaml, or smile.

When set to true will output available columns. This option can't be combined with any other query string option.

When set to true will enable verbose output.

Sets the units for columns that contain a byte-size value. Note that byte-size value units work in terms of powers of 1024. For instance 1kb means 1024 bytes, not 1000 bytes. If omitted, byte-size values are rendered with a suffix such as kb, mb, or gb, chosen such that the numeric value of the column is as small as possible whilst still being at least 1.0. If given, byte-size values are rendered as an integer with no suffix, representing the value of the column in the chosen unit. Values that are not an exact multiple of the chosen unit are rounded down.
