+<p>The Drill Metastore stores several types of metadata, called components. Currently, only the <code class="language-plaintext highlighter-rouge">tables</code> component is implemented.
+The <code class="language-plaintext highlighter-rouge">tables</code> component provides metadata about Drill tables, including their segments, files, row groups and partitions.
+In Drill <code class="language-plaintext highlighter-rouge">tables</code> component unit is represented by <code class="language-plaintext highlighter-rouge">TableMetadataUnit</code> class which is applicable to any metadata type.
+The <code class="language-plaintext highlighter-rouge">TableMetadataUnit</code> class holds fields for all five metadata types within the <code class="language-plaintext highlighter-rouge">tables</code> component. 
+Any fields not applicable to a particular metadata type are simply ignored and remain unset.</p>
 
-<p>Iceberg table generates metadata for each modification operation:
-snapshot, manifest file, table metadata file. Also when performing delete operation,
-previously stored data files are not deleted. These files with the time can occupy lots of space.
-Two table properties <code class="language-plaintext highlighter-rouge">write.metadata.delete-after-commit.enabled</code> and <code class="language-plaintext highlighter-rouge">write.metadata.previous-versions-max</code>
-control expiration process. Metadata files will be expired automatically if
-<code class="language-plaintext highlighter-rouge">write.metadata.delete-after-commit.enabled</code> is enabled.</p>
+<p>In the Mongo implementation of the Drill Metastore, all metadata of the tables component stored in
+ one collection named <code class="language-plaintext highlighter-rouge">tables</code> in the <code class="language-plaintext highlighter-rouge">meta</code> database. The database and collection will be auto
+  created when first write data into it.</p>

+<p>The Drill Metastore stores several types of metadata, called components. Currently, only the <code class="language-plaintext highlighter-rouge">tables</code> component is implemented.
+The <code class="language-plaintext highlighter-rouge">tables</code> component provides metadata about Drill tables, including their segments, files, row groups and partitions.
+In Drill <code class="language-plaintext highlighter-rouge">tables</code> component unit is represented by <code class="language-plaintext highlighter-rouge">TableMetadataUnit</code> class which is applicable to any metadata type.
+The <code class="language-plaintext highlighter-rouge">TableMetadataUnit</code> class holds fields for all five metadata types within the <code class="language-plaintext highlighter-rouge">tables</code> component. 
+Any fields not applicable to a particular metadata type are simply ignored and remain unset.</p>
 
-<p>Iceberg table generates metadata for each modification operation:
-snapshot, manifest file, table metadata file. Also when performing delete operation,
-previously stored data files are not deleted. These files with the time can occupy lots of space.
-Two table properties <code class="language-plaintext highlighter-rouge">write.metadata.delete-after-commit.enabled</code> and <code class="language-plaintext highlighter-rouge">write.metadata.previous-versions-max</code>
-control expiration process. Metadata files will be expired automatically if
-<code class="language-plaintext highlighter-rouge">write.metadata.delete-after-commit.enabled</code> is enabled.</p>
+<p>In the Mongo implementation of the Drill Metastore, all metadata of the tables component stored in
+ one collection named <code class="language-plaintext highlighter-rouge">tables</code> in the <code class="language-plaintext highlighter-rouge">meta</code> database. The database and collection will be auto
+  created when first write data into it.</p>
