Use "cbt help <command>" for more information about a command.

The options are:

-project string
	project ID, if unset uses gcloud configured project
-instance string
	Cloud Bigtable instance
-creds string
	if set, use application credentials in this file

Alpha features are not currently available to most Cloud Bigtable customers. The features might be changed in backward-incompatible ways and are not recommended for production use. They are not subject to any SLA or deprecation policy.

For convenience, values of the -project, -instance, -creds, -admin-endpoint and -data-endpoint flags may be specified in /usr/local/google/home/igorbernstein/.cbtrc in this format:

project = my-project-123
instance = my-instance
creds = path-to-account-key.json
admin-endpoint = hostname:port
data-endpoint = hostname:port

All values are optional, and all will be overridden by flags.

Count rows in a table

Usage:

cbt count <table>

Create an instance with an initial cluster

Usage:

cbt createinstance <instance-id> <display-name> <cluster-id> <zone> <num-nodes> <storage type>
  instance-id					Permanent, unique id for the instance
  display-name	  			Description of the instance
  cluster-id						Permanent, unique id for the cluster in the instance
  zone				  				The zone in which to create the cluster
  num-nodes	  				The number of nodes to create
  storage-type					SSD or HDD

Create a cluster in the configured instance (replication alpha)

  cluster-id		Permanent, unique id for the cluster in the instance
  zone				  The zone in which to create the cluster
  num-nodes	  The number of nodes to create
  storage-type	SSD or HDD

Create a column family

Usage:

Create a table

Usage:

cbt createtable <table> [families=family[:(maxage=<d> | maxversions=<n>)],...] [splits=split,...]
  families: Column families and their associated GC policies. See "setgcpolicy".
  					 Example: families=family1:maxage=1w,family2:maxversions=1
  splits:   Row key to be used to initially split the table

Update a cluster in the configured instance

Usage:

cbt updatecluster <cluster-id> [num-nodes=num-nodes]
  cluster-id		Permanent, unique id for the cluster in the instance
  num-nodes		The number of nodes to update to

Deletes an instance

Usage:

cbt deleteinstance <instance>

Deletes a cluster from the configured instance (replication alpha)

Usage:

cbt deletecluster <cluster>

Delete all cells in a column

Usage:

cbt deletecolumn <table> <row> <family> <column> [app-profile=<app profile id>]
  app-profile=<app profile id>		The app profile id to use for the request (replication alpha)

Delete a column family

Usage:

cbt deletefamily <table> <family>

Delete a row

Usage:

cbt deleterow <table> <row> [app-profile=<app profile id>]
  app-profile=<app profile id>		The app profile id to use for the request (replication alpha)

Usage:

cbt doc

Print help text

Usage:

cbt help [command]

List instances in a project

Usage:

cbt listinstances

List instances in an instance

Usage:

cbt listclusters

  end=<row>		Stop reading before this row
  prefix=<prefix>	Read rows with this prefix
  regex=<regex> 	Read rows with keys matching this regex
  count=<n>		Read only this many rows
  app-profile=<app profile id>		The app profile id to use for the request (replication alpha)

Set value of a cell

Usage:

cbt set <table> <row> [app-profile=<app profile id>] family:column=val[@ts] ...
  app-profile=<app profile id>		The app profile id to use for the request (replication alpha)
  family:column=val[@ts] may be repeated to set multiple cells.

  ts is an optional integer timestamp.
  If it cannot be parsed, the `@ts` part will be
  interpreted as part of the value.
