Variables

var (
	Attrs = FlagInfo{
		Name: "attrs",
		Description: `
An ordered, colon-separated list of node attributes. Attributes are arbitrary
strings specifying machine capabilities. Machine capabilities might include
specialized hardware or number of cores (e.g. "gpu", "x16c"). For example:
<PRE>

  --attrs=x16c:gpu`,
	}

Not fully implemented. https://github.com/cockroachdb/cockroach/issues/4868
An ordered, comma-separated list of key-value pairs that describe the topography
of the machine. Topography might include country, datacenter or rack
designations. Data is automatically replicated to maximize diversities of each
tier. The order of tiers is used to determine the priority of the diversity. The
tiers and order must be the same on all nodes.  For example:
<PRE>

  --locality=country=us,region=us-west,datacenter=us-west-1b,rack=12
  --locality=country=ca,region=ca-east,datacenter=ca-east-2,rack=4

accept requests.`,
	}

	SQLMem = FlagInfo{
		Name: "max-sql-memory",
		Description: `
Total size in bytes available for use to store temporary data for SQL
clients, including prepared queries and intermediate data rows during

Dumps the data as of the specified timestamp. Formats supported are the same
as the timestamp type.`,
	}

	Execute = FlagInfo{
		Name:      "execute",
		Shorthand: "e",
		Description: `
Execute the SQL statement(s) on the command line, then exit. This flag may be
specified multiple times and each value may contain multiple semicolon
separated statements. If an error occurs in any statement, the command exits
with a non-zero status code and further statements are not executed. The

open "<given path>/.s.PGSQL.<server port>"`,
	}

	Insecure = FlagInfo{
		Name:   "insecure",
		EnvVar: "COCKROACH_INSECURE",
		Description: `

	Key = FlagInfo{
		Name:        "key",
		EnvVar:      "COCKROACH_KEY",
		Description: `Path to the key protecting --cert. Needed in secure mode.`,
	}

	Store = FlagInfo{
		Name:      "store",
		Shorthand: "s",
		Description: `
The file path to a storage device. This flag must be specified separately for
each storage device, for example:
<PRE>

  --store=/mnt/ssd01 --store=/mnt/ssd02 --store=/mnt/hda1

</PRE>
For each store, the "attrs" and "size" fields can be used to specify device
attributes and a maximum store size (see below). When one or both of these
fields are set, the "path" field label must be used for the path to the storage
device, for example:
<PRE>

  --store=path=/mnt/ssd01,attrs=ssd,size=20GiB

</PRE>
In most cases, node-level attributes are preferable to store-level attributes.
However, the "attrs" field can be used to match capabilities for storage of
individual databases or tables. For example, an OLTP database would probably
want to allocate space for its tables only on solid state devices, whereas
append-only time series might prefer cheaper spinning drives. Typical
attributes include whether the store is flash (ssd), spinny disk (hdd), or
in-memory (mem), as well as speeds and other specs. Attributes can be arbitrary
strings separated by colons, for example:
<PRE>

  --store=path=/mnt/hda1,attrs=hdd:7200rpm

</PRE>
The store size in the "size" field is not a guaranteed maximum but is used when
calculating free space for rebalancing purposes. The size can be specified
either in a bytes-based unit or as a percentage of hard drive space,
for example:
<PRE>

  --store=path=/mnt/ssd01,size=10000000000     -> 10000000000 bytes
  --store-path=/mnt/ssd01,size=20GB            -> 20000000000 bytes
  --store-path=/mnt/ssd01,size=20GiB           -> 21474836480 bytes
  --store-path=/mnt/ssd01,size=0.02TiB         -> 21474836480 bytes
  --store=path=/mnt/ssd01,size=20%             -> 20% of available space
  --store=path=/mnt/ssd01,size=0.2             -> 20% of available space
  --store=path=/mnt/ssd01,size=.2              -> 20% of available space

</PRE>
For an in-memory store, the "type" and "size" fields are required, and the
"path" field is forbidden. The "type" field must be set to "mem", and the
"size" field must be set to the true maximum bytes or percentage of available
memory that the store may consume, for example:
<PRE>

  --store=type=mem,size=20GiB
  --store=type=mem,size=90%

</PRE>
Commas are forbidden in all values, since they are used to separate fields.
Also, if you use equal signs in the file path to a store, you must use the
"path" field label.`,

	URL = FlagInfo{
		Name:   "url",
		EnvVar: "COCKROACH_URL",
		Description: `
Connection url. eg: postgresql://myuser@localhost:26257/mydb
If left empty, the connection flags are used (host, port, user,
database, insecure, certs).`,
	}

	User = FlagInfo{
		Name:        "user",
		Shorthand:   "u",
		EnvVar:      "COCKROACH_USER",
		Description: `Database user name.`,
	}

	From = FlagInfo{
		Name: "from",
		Description: `
Start key and format as [<format>:]<key>. Supported formats: raw, human,
rangeID. The raw format supports escaped text. For example, "raw:\x01k" is the
prefix for range local keys.`,
	}

	To = FlagInfo{
		Name: "to",
		Description: `
Exclusive end key and format as [<format>:]<key>. Supported formats: raw,

		Description: `Print key and value sizes along with their associated key.`,

		Name:        "undo",
		Description: `Attempt to undo an earlier attempt to freeze the cluster.`,
