Class BigtableTableAdminClient

java.lang.Object

com.google.cloud.bigtable.admin.v2.BigtableTableAdminClient

All Implemented Interfaces:

AutoCloseable

public final class BigtableTableAdminClient
extends Object
implements AutoCloseable

Client for creating, configuring, and deleting Cloud Bigtable tables

Provides access to the table schemas only, not the data stored within the tables.

See the individual methods for example code.

Sample code to get started:

 try(BigtableTableAdminClient client =  BigtableTableAdminClient.create("[PROJECT]", "[INSTANCE]")) {
   CreateTable request =
     CreateTableRequest.of("my-table")
       .addFamily("cf1")
       .addFamily("cf2", GCRULES.maxVersions(10))
       .addSplit(ByteString.copyFromUtf8("b"))
       .addSplit(ByteString.copyFromUtf8("q"));
   client.createTable(request);
 }
 

Note: close() needs to be called on the client object to clean up resources such as threads. In the example above, try-with-resources is used, which automatically calls close().

This class can be customized by passing in a custom instance of BigtableTableAdminSettings to create(). For example:

To customize credentials:

 BigtableTableAdminSettings tableAdminSettings = BigtableTableAdminSettings.newBuilder()
   .setProjectId("[PROJECT]")
   .setInstanceId("[INSTANCE]")
   .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
   .build();

 BigtableTableAdminClient client =
   BigtableTableAdminClient.create(tableAdminSettings);
 

To customize the endpoint:

 BigtableTableAdminSettings tableAdminSettings = BigtableTableAdminSettings.newBuilder()
   .setProjectId("[PROJECT]")
   .setInstanceId("[INSTANCE]")
   .setEndpoint(myEndpoint).build();

 BigtableTableAdminClient client = BigtableTableAdminClient.create(tableAdminSettings);
