Updates the configuration of an Active-Active database.

```sh
crdb-cli crdb update --crdb-guid <guid>
         [--no-wait]
         [--force]
         [--default-db-config <configuration> ]
         [--default-db-config-file <filename>]
         [--compression <0-6>]
         [--causal-consistency { true | false } ]
         [--credentials id=<id>,username=<username>,password=<password> ]
         [--encryption { true | false } ]
         [--oss-cluster { true | false } ]
         [--featureset-version { true | false } ]
         [--memory-size <maximum_memory>]
         [--bigstore-ram-size <maximum_memory>]
         [--eviction-policy { noeviction | allkeys-lru | allkeys-lfu | allkeys-random | volatile-lru | volatile-lfu | volatile-random | volatile-ttl }]
         [--update-module name=<name>,featureset_version=<version>]
```

If you want to change the configuration of the local instance only, use [`rladmin`]({{< relref "/operate/rs/7.4/references/cli-utilities/rladmin" >}}) instead.

### Returns

Returns the task ID of the task that is updating the database.

If `--no-wait` is specified, the command exits. Otherwise, it will wait for the database to be updated and then return "finished."

### Example

```sh
$ crdb-cli crdb update --crdb-guid 968d586c-e12d-4b8f-8473-42eb88d0a3a2 --memory-size 2GBTask 7e98efc1-8233-4578-9e0c-cdc854b8af9e created
  ---> Status changed: queued -> started
  ---> Status changed: started -> finished
