+**Property:** `parquet.size.statistics.enabled`
+**Description:** Whether to enable size statistics collection.
+If `true`, size statistics will be collected for all columns unless explicitly disabled for specific columns.
+If `false`, size statistics will be disabled for all columns regardless of column-specific settings.
+It is possible to enable or disable size statistics for specific columns by appending `#` followed by the column path.
+**Default value:** `true`
+**Example:**
+```java
+// Enable size statistics for all columns
+conf.set("parquet.size.statistics.enabled", true);
+// Disable size statistics for 'column.path'
+conf.set("parquet.size.statistics.enabled#column.path", false);
+// The final configuration will be: Enable size statistics for all columns except 'column.path'
