+### Dynamic table creating
+
+When `auto_create_table` is set to `true`, try to create the table using BigQuery API when insertion failed with code=404 "Not Found: Table ...".
+Next retry of insertion is expected to be success.
+
+NOTE: `auto_create_table` option cannot be used with `fetch_schema`. You should create the table on ahead to use `fetch_schema`.
+
+```apache
+<match dummy>
+  type bigquery
+  
+  ...
+  
+  auto_create_table true
+  table accesslog_%Y_%m
+  
+  ...
+</match>
+```
