The `cbt` CLI is a command-line interface that lets you interact with Cloud Bigtable.
See the [cbt CLI overview](https://cloud.google.com/bigtable/docs/cbt-overview) to learn how to install the `cbt` CLI.
Before you use the `cbt` CLI, you should be familiar with the [Bigtable overview](https://cloud.google.com/bigtable/docs/overview).

The examples on this page use [sample data](https://cloud.google.com/bigtable/docs/using-filters#data) similar to data
that you might store in Bigtable.

Usage:

	cbt [-<option> <option-argument>] <command> <required-argument> [optional-argument]

The commands are:

	count                     Count rows in a table
	createappprofile          Create app profile for an instance
	createcluster             Create a cluster in the configured instance

	updatecluster             Update a cluster in the configured instance
	version                   Print the current cbt version
	waitforreplication        Block until all the completed writes have been replicated to all the clusters

The options are:

	-project string
	    project ID. If unset uses gcloud configured project
	-instance string
	    Cloud Bigtable instance
	-creds string
	    Path to the credentials file. If set, uses the application credentials in this file
	-timeout string
	    Timeout (e.g. 10s, 100ms, 5m )

Example:  cbt -instance=my-instance ls

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

Preview features are not currently available to most Cloud Bigtable customers. Alpha
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.

Syntax rules for the Bash shell apply to the `cbt` CLI. This means, for example,
that you must put quotes around values that contain spaces or operators. It also means that
if a value is arbitrary bytes, you need to prefix it with a dollar sign and use single quotes.

Example:

cbt -project my-project -instance my-instance lookup my-table $'\224\257\312W\365:\205d\333\2471\315\'

For convenience, you can add values for the -project, -instance, -creds, -admin-endpoint and -data-endpoint
options to your ~/.cbtrc file in the following format:

	project = my-project-123
	instance = my-instance
	creds = path-to-account-key.json
	admin-endpoint = hostname:port
	data-endpoint = hostname:port
	auth-token = AJAvW039NO1nDcijk_J6_rFXG_...
	timeout = 30s

All values are optional and can be overridden at the command prompt.

# Batch write many rows based on the input file

Usage:

	cbt import <table-id> <input-file> [app-profile=<app-profile-id>] [column-family=<family-name>] [batch-size=<500>] [workers=<1>] [timestamp=<now|value-encoded>]
	  app-profile=<app-profile-id>          The app profile ID to use for the request
	  column-family=<family-name>           The column family label to use
	  batch-size=<500>                      The max number of rows per batch write request
	  workers=<1>                           The number of worker threads
	  timestamp=<now|value-encoded>	     	Whether to use current time for all cells or interpret the timestamp from cell value. Defaults to 'now'.

	  Import data from a CSV file into an existing Cloud Bigtable table that already has the column families your data requires.

	  The CSV file can support two rows of headers:
	      - (Optional) column families
	      - Column qualifiers
	  Because the first column is reserved for row keys, leave it empty in the header rows.
	  In the column family header, provide each column family once; it applies to the column it is in and every column to the right until another column family is found.
	  Each row after the header rows should contain a row key in the first column, followed by the data cells for the row.
	  See the example below. If you don't provide a column family header row, the column header is your first row and your import command must include the `column-family` flag to specify an existing column family.

	  The timestamp for each cell will default to current time (timestamp=now), to explicitly set the timestamp for cells, set timestamp=value-encoded use <val>[@<timestamp>] as the value for the cell.
	  If no timestamp is delimited for a cell, current time will be used. If the timestamp cannot be parsed, '@<timestamp>' will be interpreted as part of the value.
	  For most uses, a timestamp is the number of microseconds since 1970-01-01 00:00:00 UTC.

	    ,column-family-1,,column-family-2,      // Optional column family row (1st cell empty)
	    ,column-1,column-2,column-3,column-4    // Column qualifiers row (1st cell empty)
	    a,TRUE,,,FALSE                          // Rowkey 'a' followed by data
	    b,,,TRUE,FALSE                          // Rowkey 'b' followed by data
	    c,,TRUE,,TRUE                           // Rowkey 'c' followed by data
	    d,TRUE@1577862000000000,,,FALSE		 	// Rowkey 'd' followed by data

	  Examples:
	    cbt import csv-import-table data.csv
	    cbt import csv-import-table data-no-families.csv app-profile=batch-write-profile column-family=my-family workers=5

	  cells-per-column=<n>                Read only this many cells per column
	  app-profile=<app-profile-id>        The app profile ID to use for the request
	  format-file=<path-to-format-file>   The path to a format-configuration file to use for the request
	  keys-only=<true|false>              Whether to print only row keys
	  include-stats=full                  Include a summary of request stats at the end of the request

	    Examples: (see 'set' examples to create data to read)
	      cbt read mobile-time-series prefix=phone columns=stats_summary:os_build,os_name count=10
	      cbt read mobile-time-series start=phone#4c410523#20190501 end=phone#4c410523#20190601
	      cbt read mobile-time-series regex="phone.*" cells-per-column=1
	      cbt read mobile-time-series start=phone#4c410523#20190501 end=phone#4c410523#20190601 reversed=true count=10

	   Note: Using a regex without also specifying start, end, prefix, or count results in a full
	   table scan, which can be slow.

Set value of a cell (write)

Usage:

	cbt set <table-id> <row-key> [app-profile=<app-profile-id>] <family>:<column>=<val>[@<timestamp>] ...
	  app-profile=<app profile id>          The app profile ID to use for the request
	  <family>:<column>=<val>[@<timestamp>] may be repeated to set multiple cells.

	    timestamp is an optional integer.
	    If the timestamp cannot be parsed, '@<timestamp>' will be interpreted as part of the value.
	    For most uses, a timestamp is the number of microseconds since 1970-01-01 00:00:00 UTC.

	    Examples:
	      cbt set mobile-time-series phone#4c410523#20190501 stats_summary:connected_cell=1@12345 stats_summary:connected_cell=0@1570041766
	      cbt set mobile-time-series phone#4c410523#20190501 stats_summary:os_build=PQ2A.190405.003 stats_summary:os_name=android

Add a value to an aggregate cell (write)

Usage:

	cbt addtocell <table-id> <row-key> [app-profile=<app-profile-id>] <family>:<column>=<val>[@<timestamp>] ...
	  app-profile=<app profile id>          The app profile ID to use for the request
	  <family>:<column>=<val>[@<timestamp>] may be repeated to set multiple cells.

	    If <val> can be parsed as an integer it will be used as one, otherwise the call will fail.
	    timestamp is an optional integer.
	    If the timestamp cannot be parsed, '@<timestamp>' will be interpreted as part of the value.
	    For most uses, a timestamp is the number of microseconds since 1970-01-01 00:00:00 UTC.

	    Examples:
	      cbt addtocell table1 user1 sum_cf:col1=1@12345

# Set the garbage-collection policy (age, versions) for a column family

Usage:

	cbt setgcpolicy <table> <family> ((maxage=<d> | maxversions=<n>) [(and|or) (maxage=<d> | maxversions=<n>),...] | never)
	  maxage=<d>         Maximum timestamp age to preserve. Acceptable units: ms, s, m, h, d
	  maxversions=<n>    Maximum number of versions to preserve
	  Put garbage collection policies in quotes when they include shell operators && and ||.

	    Examples:
	      cbt setgcpolicy mobile-time-series stats_detail maxage=10d
	      cbt setgcpolicy mobile-time-series stats_summary maxage=10d or maxversions=1

# 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 new number of nodes

	    Example: cbt updatecluster my-instance-c1 num-nodes=5
