<p>Gets multiple documents. Documents returned by this method are not guaranteed to be returned in the same order that they were requested.</p>
<h1 id="scopes">Scopes</h1>
<p>You will need authorization for at least one of the following scopes to make a valid call:</p>
<ul>
<li><em>https://www.googleapis.com/auth/cloud-platform</em></li>
<li><em>https://www.googleapis.com/auth/datastore</em></li>
</ul>
<p>If unset, the scope for this method defaults to <em>https://www.googleapis.com/auth/cloud-platform</em>.
You can set the scope for this method like this: <code>firestore1-beta1 --scope &lt;scope&gt; projects databases-documents-batch-get ...</code></p>
<h1 id="required-scalar-argument">Required Scalar Argument</h1>
<ul>
<li><strong>&lt;database&gt;</strong> <em>(string)</em><ul>
<li>Required. The database name. In the format: <code>projects/{project_id}/databases/{database_id}</code>.</li>
</ul>
</li>
</ul>
<h1 id="required-request-value">Required Request Value</h1>
<p>The request value is a data-structure with various fields. Each field may be a simple scalar or another data-structure.
In the latter case it is advised to set the field-cursor to the data-structure's field to specify values more concisely.</p>
<p>For example, a structure like this:</p>
<pre><code>BatchGetDocumentsRequest:
documents: [string]
mask:
field-paths: [string]
new-transaction:
read-only:
read-time: string
read-write:
retry-transaction: string
read-time: string
transaction: string
</code></pre>
<p>can be set completely with the following arguments which are assumed to be executed in the given order. Note how the cursor position is adjusted to the respective structures, allowing simple field names to be used most of the time.</p>
<ul>
<li><code>-r . documents=et</code><ul>
<li>The names of the documents to retrieve. In the format: <code>projects/{project_id}/databases/{database_id}/documents/{document_path}</code>. The request will fail if any of the document is not a child resource of the given <code>database</code>. Duplicate names will be elided.</li>
<li>Each invocation of this argument appends the given value to the array.</li>
</ul>
</li>
<li>
<p><code>mask field-paths=magna</code></p>
<ul>
<li>The list of field paths in the mask. See Document.fields for a field path syntax reference.</li>
<li>Each invocation of this argument appends the given value to the array.</li>
</ul>
</li>
<li>
<p><code>..new-transaction.read-only read-time=no</code></p>
<ul>
<li>Reads documents at the given time. This may not be older than 60 seconds.</li>
</ul>
</li>
<li>
<p><code>..read-write retry-transaction=ipsum</code></p>
<ul>
<li>An optional transaction to retry.</li>
</ul>
</li>
<li>
<p><code>... read-time=voluptua.</code></p>
<ul>
<li>Reads documents as they were at the given time. This may not be older than 270 seconds.</li>
</ul>
</li>
<li><code>transaction=at</code><ul>
<li>Reads documents in a transaction.</li>
</ul>
</li>
</ul>
<h3 id="about-cursors">About Cursors</h3>
<p>The cursor position is key to comfortably set complex nested structures. The following rules apply:</p>
<ul>
<li>The cursor position is always set relative to the current one, unless the field name starts with the <code>.</code> character. Fields can be nested such as in <code>-r f.s.o</code> .</li>
<li>The cursor position is set relative to the top-level structure if it starts with <code>.</code>, e.g. <code>-r .s.s</code></li>
<li>You can also set nested fields without setting the cursor explicitly. For example, to set a value relative to the current cursor position, you would specify <code>-r struct.sub_struct=bar</code>.</li>
<li>You can move the cursor one level up by using <code>..</code>. Each additional <code>.</code> moves it up one additional level. E.g. <code>...</code> would go three levels up.</li>
</ul>
<h1 id="optional-output-flags">Optional Output Flags</h1>
<p>The method's return value a JSON encoded structure, which will be written to standard output by default.</p>
<ul>
<li><strong>-o out</strong><ul>
<li><em>out</em> specifies the <em>destination</em> to which to write the server's result to.
It will be a JSON-encoded structure.
The <em>destination</em> may be <code>-</code> to indicate standard output, or a filepath that is to contain the received bytes.
If unset, it defaults to standard output.</li>
</ul>
</li>
</ul>
<h1 id="optional-general-properties">Optional General Properties</h1>
