2. Use the credentials provided by InfluxData to log into the Admin UI. If you don't have login credentials, [contact InfluxData support](https://support.influxdata.com). After you log in, the Account Management portal displays [account information](/influxdb3/cloud-dedicated/admin/account/) and lists all clusters associated with your account. 3. Click a cluster row to view the list of databases associated with the cluster. You can **Search** for clusters by name or ID to filter the list and use the sort button and column headers to sort the list. 4. Find the database you want to update. You can **Search** for databases by name or ID to filter the list and use the sort button and column headers to sort the list. 5. To set the retention period, click the options button (3 vertical dots) to the right of the database. 6. In the options menu, click **Set Retention Period**. {{% /tab-content %}} {{% tab-content %}} Use the [`influxctl database update` command](/influxdb3/cloud-dedicated/reference/cli/influxctl/database/update/) to update a database in your {{< product-name omit=" Clustered" >}} cluster. 1. If you haven't already, [download and install the `influxctl` CLI](/influxdb3/cloud-dedicated/reference/cli/influxctl/#download-and-install-influxctl). 2. In your terminal, run the `influxctl database update` command and provide the following: - Database name - _Optional_: Database [retention period](/influxdb3/cloud-dedicated/admin/databases/#retention-periods). Default is infinite (`0`). - _Optional_: Database [table (measurement) limit](/influxdb3/cloud-dedicated/admin/databases/#table-limit). Default is `500`. - _Optional_: Database [column limit](/influxdb3/cloud-dedicated/admin/databases/#column-limit). Default is `250`. {{% code-placeholders "DATABASE_NAME|30d|500|200" %}} ```sh influxctl database update \ --retention-period 30d \ --max-tables 500 \ --max-columns 250 \ DATABASE_NAME ``` {{% /code-placeholders %}} Replace the following in your command: - {{% code-placeholder-key %}}`DATABASE_NAME`{{% /code-placeholder-key %}}: your {{% product-name %}} [database](/influxdb3/cloud-dedicated/admin/databases/) > [!Warning] > #### Database names can't be updated > > The `influxctl database update` command uses the database name to identify which > database to apply updates to.

The retention period value is an integer (``) that represents the number of nanoseconds. For example, `2592000000000` means 30 days. A zero (`0`) retention period is infinite and data won't expire. The retention period value cannot be negative or contain whitespace. #### Example retention period values - `0`: infinite/none - `259200000000000`: 3 days - `2592000000000000`: 30 days - `31536000000000000`: 1 standard year (365 days) {{% /tab-content %}} {{< /tabs-wrapper >}} > [!Warning] > > #### Database names can't be updated > > The Management API `PATCH /api/v0/database` endpoint and > the`influxctl database update` command use the database name to identify which > database to apply updates to. > The database name itself can't be updated. > > #### Partition templates can't be updated > > You can only apply a partition template when creating a database. > You can't update a partition template on an existing database. ### Database naming restrictions Database names must adhere to the following naming restrictions: - Cannot contain whitespace, punctuation, or special characters. Only alphanumeric, underscore (`_`), dash (`-`), and forward-slash (`/`) characters are permitted. - Should not start with an underscore (`_`). - Maximum length of 64 characters. ### InfluxQL DBRP naming convention In InfluxDB 1.x, data is stored in [databases](/influxdb/v1/concepts/glossary/#database) and [retention policies](/influxdb/v1/concepts/glossary/#retention-policy-rp). In {{< product-name >}}, databases and retention policies have been merged into _databases_, where databases have a retention period, but retention policies are no longer part of the data model. Because InfluxQL uses the 1.x data model, a database must be mapped to a v1 database and retention policy (DBRP) to be queryable with InfluxQL. **When naming a database that you want to query with InfluxQL**, use the following naming convention to automatically map v1 DBRP combinations to a database: ```text database_name/retention_policy_name ``` #### Database naming examples | v1 Database name | v1 Retention Policy name | New database name | | :--------------- | :----------------------- | :------------------------ | | db | rp | db/rp | | telegraf | autogen | telegraf/autogen | | webmetrics | 1w-downsampled | webmetrics/1w-downsampled | ### Table and column limits In {{< product-name >}}, table (measurement) and column limits can be configured using the following options: | Description | Default | influxctl CLI flag | Management API property | | :---------------------------- | :------ | :-------------- | :------------------- | | [Table limit](#table-limit) | 500 | `--max-tables` | `maxTables` | | [Column limit](#column-limit) | 250 | `--max-columns` | `maxColumnsPerTable` | #### Table limit **Default maximum number of tables**: 500 Each measurement is represented by a table in a database. Your database's table limit can be raised beyond the default limit of 500. InfluxData has production examples of clusters with 20,000+ active tables across multiple databases. Increasing your table limit affects your {{% product-name omit=" Clustered" %}} cluster in the following ways: {{< expand-wrapper >}} {{% expand "**May improve query performance** View more info" %}} Schemas with many measurements that contain [focused sets of tags and fields](/influxdb3/cloud-dedicated/write-data/best-practices/schema-design/#design-for-performance) can make it easier for the query engine to identify what partitions contain the queried data, resulting in better query performance. {{% /expand %}} {{% expand "**More PUTs into object storage** View more info" %}} By default, {{< product-name >}} partitions data by measurement and time range and stores each partition as a Parquet file in your cluster's object store. By increasing the number of measurements (tables) you can store in your database, you also increase the potential for more `PUT` requests into your object store as InfluxDB creates more partitions. Each `PUT` request incurs a monetary cost and will increase the operating cost of your cluster. {{% /expand %}} {{% expand "**More work for the compactor** View more info" %}} To optimize storage over time, your {{< product-name omit=" Clustered" >}} cluster contains a compactor that routinely compacts Parquet files in object storage. With more tables and partitions to compact, the compactor may need to be scaled (either vertically or horizontally) to keep up with demand, adding to the operating cost of your cluster. {{% /expand %}} {{< /expand-wrapper >}} #### Column limit **Default maximum number of columns**: 250 Time, fields, and tags are each represented by a column in a table. Increasing your column limit affects your {{% product-name omit=" Clustered" %}} cluster in the following ways: {{< expand-wrapper >}} {{% expand "May adversely affect query performance" %}} At query time, the InfluxDB query engine identifies what table contains the queried data and then evaluates each row in the table to match the conditions of the query. The more columns that are in each row, the longer it takes to evaluate each row. Through performance testing, InfluxData has identified 250 columns as the threshold beyond which query performance may be affected (depending on the shape of and data types in your schema). {{% /expand %}} {{< /expand-wrapper >}}
