Dans ce guide de démarrage rapide, vous effectuez les actions suivantes :
Connexion à une instance Bigtable
Tâches d'administration de base
Écriture de données dans une table
Lecture des données d'une table

Dans le champ Nom de l'instance, saisissez Quickstart instance.
Dans le champ ID d'instance, saisissez quickstart-instance.
Cliquez sur Continuer.
Comme Type de stockage, sélectionnez SSD.
Cliquez sur Continuer.
Dans le champ ID de cluster, saisissez quickstart-instance-c1.
Dans le champ Région, sélectionnez une région à proximité de votre emplacement.
Dans le champ Zone, sélectionnez Toutes.
Dans le champ Mode de scaling des nœuds, sélectionnez Allocation manuelle.
Dans le champ Quantité, sélectionnez 1.
Cliquez sur Créer pour créer l'instance.
Se connecter à l'instance
Configurez la CLI cbt pour utiliser votre projet et votre instance en créant un fichier .cbtrc, en remplaçant PROJECT_ID par l'ID du projet dans lequel vous avez créé votre instance Bigtable :
Vous pouvez maintenant utiliser la CLI
cbt avec votre instance.
Lire et écrire des données
Bigtable enregistre les données dans des tables contenant des lignes. Chaque ligne est identifiée par une clé de ligne.
Les données d'une ligne sont organisées en familles de colonnes, qui sont des groupes de colonnes.
Un qualificatif de colonne identifie une seule colonne au sein d'une famille.
Il peut exister plusieurs cellules horodatées à l'intersection d'une ligne et d'une colonne.
Créez une table nommée my-table.
cbt createtable my-table
Répertoriez vos tables :
cbt ls
La commande affiche un résultat semblable à celui-ci :
my-table
Ajoutez une famille de colonnes nommée cf1 :
cbt createfamily my-table cf1
Répertoriez vos familles de colonnes :
cbt ls my-table
La commande affiche un résultat semblable à celui-ci :
Family Name GC Policy
----------- ---------
cf1 <never>
Écrivez les valeurs test-value1 et test-value2 dans la ligne r1 en utilisant la famille de colonnes cf1 et le qualificatif de colonne c1 :
cbt set my-table r1 cf1:c1=test-value1
cbt set my-table r1 cf1:c1=test-value2
Utilisez la commande cbt read pour lire les données que vous avez ajoutées à la table :
cbt read my-table
L'interface système affiche un résultat semblable à celui-ci :
Deux valeurs horodatées sont stockées pour la même colonne dans la ligne r1.
Effectuer un nettoyage
Pour éviter que les ressources utilisées dans ce guide de démarrage rapide ne soient facturées sur votre compte Google Cloud , supprimez l'instance. Dès lors que vous supprimez le fichier .cbtrc, vous êtes prêt à travailler sur un autre projet.
Supprimez la table my-table :
cbt deletetable my-table
Supprimez l'instance :
cbt deleteinstance quickstart-instance
Supprimez le fichier .cbtrc :
rm ~/.cbtrc
Facultatif : Révoquez les identifiants de gcloud CLI :

Open the **Create instance** page in the Google Cloud console.\n\n [Create an instance](https://console.cloud.google.com/bigtable/create-instance)\n2. For **Instance name** , enter `Quickstart instance`.\n\n3. For **Instance ID** , enter `quickstart-instance`.\n\n4. Click **Continue**.\n\n5. For **Storage type** , select **SSD**.\n\n6. Click **Continue**.\n\n7. For **Cluster ID** , enter `quickstart-instance-c1`.\n\n8. For **Region**, select a region near you.\n\n9. For **Zone** , select **Any**.\n\n10. For **Node scaling mode** , choose **Manual allocation**.\n\n11. For **Quantity** , select **1**.\n\n12. Click **Create** to create the instance.\n\nConnect to your instance\n\n1. Configure the\n `cbt` CLI\n to use your project and instance by creating a\n `.cbtrc` file, replacing \u003cvar translate=\"no\"\u003ePROJECT_ID\u003c/var\u003e with the ID\n for the project where you created your Bigtable instance:\n\n ```\n echo project = PROJECT_ID \u003e\u003e ~/.cbtrc && echo instance = quickstart-instance \u003e\u003e ~/.cbtrc\n ```\n2. Verify that you set up the `.cbtrc` file correctly:\n\n ```\n cat ~/.cbtrc\n ```\n\n The terminal displays the contents of the `.cbtrc` file, which looks similar\n to the following: \n\n ```\n project = PROJECT_ID\n instance = quickstart-instance\n ```\n\n Now you can use the\n `cbt` CLI\n with your instance.\n\nRead and write data\n\nBigtable stores data in *tables* , which contain *rows* . Each row\nis identified by a *row key*.\n\nData in a row is organized into *column families* , which are groups of columns.\nA *column qualifier* identifies a single column within a column family.\n\nThere can be multiple time-stamped cells at the intersection of\na row and column.\n\n1. Create a table named `my-table`.\n\n ```\n cbt createtable my-table\n ```\n2. List your tables:\n\n ```\n cbt ls\n ```\n\n The command displays output similar to the following:\n\n \u003cbr /\u003e\n\n ```\n my-table\n ```\n\n \u003cbr /\u003e\n\n3. Add one column family named `cf1`:\n\n ```\n cbt createfamily my-table cf1\n ```\n4. List your column families:\n\n ```\n cbt ls my-table\n ```\n\n The command displays output similar to the following:\n\n \u003cbr /\u003e\n\n ```\n Family Name GC Policy\n ----------- ---------\n cf1 \u003cnever\u003e\n ```\n\n \u003cbr /\u003e\n\n5. Write the values `test-value1` and `test-value2` to the row `r1`, using the\n column family `cf1` and the column qualifier `c1`:\n\n ```\n cbt set my-table r1 cf1:c1=test-value1\n cbt set my-table r1 cf1:c1=test-value2\n ```\n6. Use the `cbt read` command to read the data you added to the table:\n\n ```\n cbt read my-table\n ```\n\n The shell displays output similar to the following:\n\n \u003cbr /\u003e\n\n ```\n ----------------------------------------\n r1\n cf1:c1 @ 2023/03/22-06:56:11.323000\n \"test-value1\"\n cf1:c1 @ 2023/03/22-06:56:04.361000\n \"test-value2\"\n ```\n\n \u003cbr /\u003e\n\n Two timestamped values are stored for the same column in row `r1`.\n | **Note:** In this quickstart you set only two cells, but Bigtable lets you set up to 10,000 cells in a single write request.\n\nClean up\n\nTo avoid incurring charges to your Google Cloud account for the resources\nused in this quickstart, delete the instance. Deleting the `.cbtrc` file leaves\nyou ready to work on a different project.\n\n1. Delete the table `my-table`:\n\n ```\n cbt deletetable my-table\n ```\n2. Delete the instance:\n\n ```\n cbt deleteinstance quickstart-instance\n ```\n3. Delete the `.cbtrc` file:\n\n ```\n rm ~/.cbtrc\n ```\n\n \u003cbr /\u003e\n\n4. Optional: Revoke credentials from the gcloud CLI:\n\n ```\n gcloud auth revoke\n ```\n\nWhat's next\n\n- Work through a [Bigtable codelab](https://codelabs.developers.google.com/codelabs/cloud-bigtable-intro-java/index.html).\n- View the [`cbt` CLI\n reference documentation](/bigtable/docs/cbt-reference).\n- See sample source code for a [fraud detection use case](https://github.com/GoogleCloudPlatform/java-docs-samples/tree/main/bigtable/use-cases/fraudDetection).\n- Write a Hello World application in [C#](/bigtable/docs/samples-c-sharp-hello), [C++](/bigtable/docs/samples-cpp-hello), [Go](/bigtable/docs/samples-go-hello), [Java](/bigtable/docs/samples-java-hello-world), [Node.js](/bigtable/docs/samples-nodejs-hello), [PHP](/bigtable/docs/samples-php-hello), [Python](/bigtable/docs/samples-python-hello), [Ruby](/bigtable/docs/samples-ruby-hello), or using the [HBase client for Java](/bigtable/docs/samples-hbase-java-hello)."]]
