If you want to change the configuration of the local instance only, use [rladmin]({{< relref "/operate/rs/7.4/references/cli-utilities/rladmin" >}}) instead.
| 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]({{< relref "/operate/rs/7.4/databases/active-active/causal-consistency.md" >}}) 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 | | 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]({{< relref "/operate/rs/7.4/databases/memory-performance/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 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."
