Cloud Bigtable V2 Client - Class BigtableTableAdminClient (1.23.0)

Reference documentation and code samples for the Cloud Bigtable V2 Client class BigtableTableAdminClient.

Service Description: Service for creating, configuring, and deleting Cloud Bigtable tables.

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

This class provides the ability to make remote calls to the backing service through method calls that map to API methods. Sample code to get started:

$bigtableTableAdminClient = new Google\Cloud\Bigtable\Admin\V2\BigtableTableAdminClient();
try {
    $formattedName = $bigtableTableAdminClient->tableName('[PROJECT]', '[INSTANCE]', '[TABLE]');
    $consistencyToken = 'consistency_token';
    $response = $bigtableTableAdminClient->checkConsistency($formattedName, $consistencyToken);
} finally {
    $bigtableTableAdminClient->close();
}

Many parameters require resource names to be formatted in a particular way. To assist with these names, this class includes a format method for each type of name, and additionally a parseName method to extract the individual identifiers contained within formatted names that are returned by the API.

    }
    // Alternatively:
    // start the operation, keep the operation name, and resume later
    $operationResponse = $bigtableTableAdminClient->createBackup($formattedParent, $backupId, $backup);
    $operationName = $operationResponse->getName();
    // ... do other work

}

Parameters
Name	Description
`parent`	`string` Required. The cluster to list backups from. Values are of the form `projects/{project}/instances/{instance}/clusters/{cluster}`. Use `{cluster} = '-'` to list backups for all clusters in an instance, e.g., `projects/{project}/instances/{instance}/clusters/-`.
`optionalArgs`	`array` Optional.
`↳ filter`	`string` A filter expression that filters backups listed in the response. The expression must specify the field name, a comparison operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The comparison operator must be <, >, <=, >=, !=, =, or :. Colon ':' represents a HAS operator which is roughly synonymous with equality. Filter rules are case insensitive. The fields eligible for filtering are: * `name` * `source_table` * `state` * `start_time` (and values are of the format YYYY-MM-DDTHH:MM:SSZ) * `end_time` (and values are of the format YYYY-MM-DDTHH:MM:SSZ) * `expire_time` (and values are of the format YYYY-MM-DDTHH:MM:SSZ) * `size_bytes` To filter on multiple expressions, provide each separate expression within parentheses. By default, each expression is an AND expression. However, you can include AND, OR, and NOT expressions explicitly. Some examples of using filters are: * `name:"exact"` --> The backup's name is the string "exact". * `name:howl` --> The backup's name contains the string "howl". * `source_table:prod` --> The source_table's name contains the string "prod". * `state:CREATING` --> The backup is pending creation. * `state:READY` --> The backup is fully created and ready for use. * `(name:howl) AND (start_time < \"2018-03-28T14:50:00Z\")` --> The backup name contains the string "howl" and start_time of the backup is before 2018-03-28T14:50:00Z. * `size_bytes > 10000000000` --> The backup's size is greater than 10GB
`↳ orderBy`	`string` An expression for specifying the sort order of the results of the request. The string value should specify one or more fields in Backup. The full syntax is described at https://aip.dev/132#ordering. Fields supported are: * name * source_table * expire_time * start_time * end_time * size_bytes * state For example, "start_time". The default sorting order is ascending. To specify descending order for the field, a suffix " desc" should be appended to the field name. For example, "start_time desc". Redundant space characters in the syntax are insigificant. If order_by is empty, results will be sorted by `start_time` in descending order starting from the most recently created backup.
`↳ pageSize`	`int` The maximum number of resources contained in the underlying API response. The API may return fewer values in a page, even if there are additional values to be retrieved.
`↳ pageToken`	`string` A page token is used to specify a page of values to be returned. If no page token is specified (the default), the first page of values will be returned. Any page token used here must have been generated by a previous call to the API.
`↳ retrySettings`	`RetrySettings\|array` Retry settings to use for this call. Can be a Google\ApiCore\RetrySettings object, or an associative array of retry settings parameters. See the documentation on Google\ApiCore\RetrySettings for example usage.

Returns

listSnapshots

Lists all snapshots associated with the specified cluster.

Sample code:

$bigtableTableAdminClient = new Google\Cloud\Bigtable\Admin\V2\BigtableTableAdminClient();
try {
    $formattedParent = $bigtableTableAdminClient->clusterName('[PROJECT]', '[INSTANCE]', '[CLUSTER]');
    // Iterate over pages of elements
    $pagedResponse = $bigtableTableAdminClient->listSnapshots($formattedParent);
    foreach ($pagedResponse->iteratePages() as $page) {
        foreach ($page as $element) {
            // doSomethingWith($element);
        }
    }
    // Alternatively:
    // Iterate through all elements
    $pagedResponse = $bigtableTableAdminClient->listSnapshots($formattedParent);
    foreach ($pagedResponse->iterateAllElements() as $element) {
        // doSomethingWith($element);
    }
} finally {
    $bigtableTableAdminClient->close();
}

Parameters
Name	Description
`parent`	`string` Required. The unique name of the cluster for which snapshots should be listed. Values are of the form `projects/{project}/instances/{instance}/clusters/{cluster}`. Use `{cluster} = '-'` to list snapshots for all clusters in an instance, e.g., `projects/{project}/instances/{instance}/clusters/-`.
`optionalArgs`	`array` Optional.
`↳ pageSize`	`int` The maximum number of resources contained in the underlying API response. The API may return fewer values in a page, even if there are additional values to be retrieved.
`↳ pageToken`	`string` A page token is used to specify a page of values to be returned. If no page token is specified (the default), the first page of values will be returned. Any page token used here must have been generated by a previous call to the API.
`↳ retrySettings`	`RetrySettings\|array` Retry settings to use for this call. Can be a Google\ApiCore\RetrySettings object, or an associative array of retry settings parameters. See the documentation on Google\ApiCore\RetrySettings for example usage.

Returns

modifyColumnFamilies

Performs a series of column family modifications on the specified table.

Either all or none of the modifications will occur before this method returns, but data requests received prior to that point may see a table where only some modifications have taken effect.

Sample code:

$bigtableTableAdminClient = new Google\Cloud\Bigtable\Admin\V2\BigtableTableAdminClient();
try {
    $formattedName = $bigtableTableAdminClient->tableName('[PROJECT]', '[INSTANCE]', '[TABLE]');

Parameters
Name	Description
`name`	`string` Required. The unique name of the table whose families should be modified. Values are of the form `projects/{project}/instances/{instance}/tables/{table}`.
`modifications`	`array<Google\Cloud\Bigtable\Admin\V2\ModifyColumnFamiliesRequest\Modification>` Required. Modifications to be atomically applied to the specified table's families.

The response type is Table, if successful.

Sample code:
