Cbt é uma ferramenta para fazer interações básicas com o Cloud Bigtable.
Utilização:
cbt [options] command [arguments]
Os comandos são:
count Count rows in a table
createinstance Create an instance with an initial cluster
createcluster Create a cluster in the configured instance
createfamily Create a column family
createtable Create a table
updatecluster Update a cluster in the configured instance
deleteinstance Delete an instance
deletecluster Delete a cluster from the configured instance
deletecolumn Delete all cells in a column
deletefamily Delete a column family
deleterow Delete a row
deletetable Delete a table
doc Print godoc-suitable documentation for cbt
help Print help text
listinstances List instances in a project
listclusters List clusters in an instance
lookup Read from a single row
ls List tables and column families
mddoc Print documentation for cbt in Markdown format
read Read rows
set Set value of a cell
setgcpolicy Set the GC policy for a column family
waitforreplication Block until all the completed writes have been replicated to all the clusters
version Print the current cbt version
createappprofile Creates app profile for an instance
getappprofile Reads app profile for an instance
listappprofile Lists app profile for an instance
updateappprofile Updates app profile for an instance
deleteappprofile Deletes app profile for an instance
Use "cbt help
As opções são:
-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
No momento, os recursos alfa não estão disponíveis para a maioria dos clientes do Cloud Bigtable. Os recursos podem ser alterados de maneiras incompatíveis com versões anteriores e não são recomendados para uso em produção. Eles não estão sujeitos a SLA ou política de suspensão de uso.
Por conveniência, os valores das sinalizações -project, -instance, -creds, -admin-endpoint e -data-endpoint são especificados em ~/.cbtrc neste formato:
project = my-project-123
instance = my-instance
creds = path-to-account-key.json
admin-endpoint = hostname:port
data-endpoint = hostname:port
Todos os valores são opcionais e serão substituídos por sinalizações.
Contar linhas em uma tabela
cbt count <table>
Criar uma instância com um cluster inicial
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
Criar um cluster na instância configurada
cbt createcluster <cluster-id> <zone> <num-nodes> <storage type>
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

Criar um grupo de colunas
cbt createfamily <table> <family>
Criar uma tabela
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

Definir valor de uma célula
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
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.
