更新 Active-Active 数据库的配置。

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>]
         [--update-module name=<name>,featureset_version=<version>]

If you want to change the configuration of the local instance only, use rladmin instead.

Parameters

Parameter Value Description
crdb-guid <guid> string GUID of the Active-Active database (required)
bigstore-ram-size <maximum_memory> size in bytes, kilobytes (KB), or gigabytes (GB) Maximum RAM limit for the databases with Auto Tiering enabled, if activated
memory-size <maximum_memory> size in bytes, kilobytes (KB), or gigabytes (GB) Maximum database memory (required)
causal-consistency true
false		 Causal consistency applies updates to all instances in the order they were received
compression 0-6 The level of data compression:

0 = No compression

6 = High compression and resource load (Default: 3)
credentials id=<id>,username=<username>,password=<password> strings Updates the credentials for access to the instance
default-db-config <configuration> Default database configuration from stdin. For a list of database settings, see the CRDB database config object reference.
default-db-config-file <filename> filepath Default database configuration from file
encryption true
false		 Activates or deactivates encryption
force Force an update even if there are no changes
no-wait Do not wait for the command to finish
oss-cluster true
false		 Activates or deactivates OSS Cluster mode
eviction-policy noeviction
allkeys-lru
allkeys-lfu
allkeys-random
volatile-lru
volatile-lfu
volatile-random
volatile-ttl		 Updates eviction policy
featureset-version true
false		 Updates to latest FeatureSet version
update-module name=<name>,featureset_version=<version> strings Update a module to the specified version

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."

Examples

The following example changes the maximum database memory:

$ crdb-cli crdb update --crdb-guid <crdb-guid> --memory-size 2GB
Task <task-id> created
  ---> Status changed: queued -> started
  ---> Status changed: started -> finished

The following example shows how to change a default database configuration setting:

$ crdb-cli crdb update --crdb-guid <crdb-guid> --default-db-config '{"shards_count": <primary_shards_count>}'
Task <task-id> created
  ---> Status changed: queued -> started
  ---> Status changed: started -> finished
