+# Alter Configuration
+## Overview
+
+Fluss provides ways to alter the configuration of a cluster or a table. You
can change and apply the configuration without restarting Fluss server. In this
section, we will show how to alter the configuration of a cluster or a table.
+
+## Alter Cluster Configuration
+
+Currently, you can only alter the configuration of a cluster with [Java
client](apis/java-client.md).
+
+Currently, only `datalake.format` and options with prefix
`datalake.${datalake.format}` can be altered. These options will also be served
as table options when getting the table info.
+
+The AlterConfig class contains three key properties:
+* key: The configuration key to be modified (e.g., `datalake.format`)
+* value: The configuration value to be set (e.g., "paimon")
+* opType: The operation type, either AlterConfigOpType.SET or
AlterConfigOpType.DELETE
+
+To disable a cluster, you can use the following code:
+```java
+admin.alterClusterConfigs(
+ Collections.singletonList(
+ new AlterConfig(DATALAKE_FORMAT.key(), "paimon",
AlterConfigOpType.SET)));
+```
+
+To disable a cluster, you can use the following code:
+```java
+admin.alterClusterConfigs(
+ Collections.singletonList(
+ new AlterConfig(DATALAKE_FORMAT.key(), "paimon",
AlterConfigOpType.DELETE)));
+```
+
+Currently, only `datalake.format` and option with prefix
`datalake.${datalake.format}` can be altered. And this options will also be
served as table options when getting the table info.
+
+## Alter Table Configuration
+
+Storage Options can be altered by [Alter
Table](engine-flink/ddl.md#alter-table). The limitations are as follows:
+1. `bootstrap.servers`,`bucket.num` and `bucket.key` cannot be altered.
