Menghubungkan ke instance
Konfigurasi
CLI cbt
untuk menggunakan project dan instance Anda dengan membuat file
.cbtrc, mengganti PROJECT_ID dengan ID
untuk project tempat Anda membuat instance Bigtable:
Dua nilai yang diberi stempel waktu disimpan untuk kolom yang sama di baris r1.
Pembersihan
Agar tidak menimbulkan biaya pada akun Google Cloud Anda untuk resource yang digunakan dalam panduan memulai ini, hapus instance. Menghapus file .cbtrc membuat Anda siap mengerjakan project lain.

Run the following command to install the `cbt` CLI : \n\n gcloud components install cbt\n\n\u003cbr /\u003e\n\nCreate a Bigtable instance\n--------------------------\n\n1. 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------------------------\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-------------------\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--------\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\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)."]]
