|
||||
## Retention periods
|
||||
|
||||
A database **retention period** is the maximum age of data stored in the database.
|
||||
The age of data is determined by the timestamp associated with each point.
|
||||
When a point's timestamp is beyond the retention period (relative to now), the
|
||||
point is marked for deletion and is removed from the database the next time the
|
||||
retention enforcement service runs.
|
||||
|
||||
The _minimum_ retention period for an InfluxDB database is 1 hour.
|
||||
The _maximum_ retention period is infinite meaning data does not expire and will
|
||||
never be removed by the retention enforcement service.
|
||||
-->
|
||||
|
||||
## Database, table, and column limits
|
||||
|
||||
{{< product-name >}} places the following limits on databases, tables, and columns:
|
||||
|
||||
### Database limit
|
||||
|
||||
**Maximum number of databases**: {{% influxdb3/limit "database" %}}
|
||||
|
||||
### Table limit
|
||||
|
||||
**Maximum number of tables across all databases**: {{% influxdb3/limit "table" %}}
|
||||
|
||||
{{< product-name >}} limits the number of tables you can have across _all_
|
||||
databases to {{% influxdb3/limit "table" %}}. There is no specific limit on how
|
||||
many tables you can have in an individual database, as long as the total across
|
||||
all databases is below the limit.
|
||||
|
||||
Having more tables affects your {{% product-name %}} installation in the
|
||||
following ways:
|
||||
|
||||
{{< expand-wrapper >}}
|
||||
{{% expand "**May improve query performance** <em style='opacity:.5;font-weight:normal;'>View more info</em>" %}}
|
||||
|
||||
Schemas with many tables that contain
|
||||
[focused sets of tags and fields](/influxdb3/version/write-data/best-practices/schema-design/#design-for-performance)
|
||||
can make it easier for the query engine to identify what Parquet files contain
|
||||
the queried data, resulting in better query performance.
|
||||
|
||||
{{% /expand %}}
|
||||
{{% expand "**More PUTs into object storage** <em style='opacity:.5;font-weight:normal;'>View more info</em>" %}}
|
||||
|
||||
When using cloud-based object storage as your data backend, the more tables you
|
||||
have, the more `PUT` requests there are into your object store as InfluxDB
|
||||
persists data to Parquet files. Each `PUT` request incurs a monetary cost and
|
||||
increases the operating cost of {{< product-name >}}.
|
||||
|
||||
{{% /expand %}}
|
||||
{{% expand "**More work for the compactor** _(Enterprise only)_ <em style='opacity:.5;font-weight:normal;'>View more info</em>" %}}
|
||||
|
||||
To optimize storage over time, InfluxDB 3 Enterprise has a compactor that
|
||||
routinely compacts Parquet files.
|
||||
With more tables and Parquet files to compact, the compactor may need to be scaled
|
||||
to keep up with demand, adding to the operating cost of InfluxDB 3 Enterprise.
|
||||
|
||||
{{% /expand %}}
|
||||
{{< /expand-wrapper >}}
|
||||
|
||||
### Column limit
|
||||
|
||||
**Maximum number of columns per table**: {{% influxdb3/limit "column" %}}
|
||||
|
||||
Each row must include a time column, with the remaining columns representing
|
||||
tags and fields.
|
||||
As a result, a table can have one time column and up to {{% influxdb3/limit "column" -1 %}}
|
||||
_combined_ field and tag columns.
|
||||
If you attempt to write to a table and exceed the column limit, the write
|
||||
request fails and InfluxDB returns an error.
|
||||
|
||||
Higher numbers of columns has the following side-effects:
|
||||
|
||||
{{< expand-wrapper >}}
|
||||
{{% expand "May adversely affect system performance" %}}
|
||||
|
||||
InfluxData identified {{% influxdb3/limit "column" %}} columns as the safe limit
|
||||
for maintaining system performance and stability.
|
||||
Exceeding this threshold can result in
|
||||
[wide schemas](/influxdb3/version/write-data/best-practices/schema-design/#avoid-wide-schemas),
|
||||
which can negatively impact performance and resource use,
|
||||
depending on your queries, the shape of your schema, and data types in the schema.

## Retention period syntax
|

|
||||
Use the `--retention-period` flag to define a specific
|
||||
[retention period](/influxdb3/version/admin/databases/#retention-periods)
|
||||
for the database.
|
||||
The retention period value is a time duration value made up of a numeric value
|
||||
plus a duration unit.
|
||||
For example, `30d` means 30 days.
|
||||
A zero duration (`0d`) retention period is infinite and data won't expire.
|
||||
The retention period value cannot be negative or contain whitespace.
|
||||
|
||||
{{< flex >}}
|
||||
{{% flex-content "half" %}}
|
||||
|
||||
##### Valid durations units include
|
||||
|
||||
- **m**: minute
|
||||
- **h**: hour
|
||||
- **d**: day
|
||||
- **w**: week

- **mo**: month
|

- **y**: year
|
||||

{{% /flex-content %}}
|
||||

##### Example retention period values
|

|
||||
- `0d`: infinite/none
|
||||
- `3d`: 3 days
|
||||
- `6w`: 6 weeks
|
||||
- `1mo`: 1 month (30 days)
|
||||
- `1y`: 1 year
|
||||
- `30d30d`: 60 days
|

- `2.5d`: 60 hours

|
||||
|
||||
## Database naming restrictions
|
||||
|
||||
Database names must adhere to the following naming restrictions:
|
||||
|
||||
- Alphanumeric characters
|
||||
- Dashes (`-`), underscores (`_`), and forward slashes (`/`) are allowed
|
||||
- Must start with a letter or number
|
||||
- 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_; retention policies are no longer part of the data model.
|
||||
Because InfluxQL uses the 1.x data model, to support InfluxQL queries the use
|
||||
databases and retention policies, an {{< product-name >}} 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 an
|
||||
{{% product-name %}} 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 |
|
||||
|
||||
## Database limit
|
||||
|
||||
**Maximum number of databases**: {{% influxdb3/limit "database" %}}

||||

### Output formats

## List deleted databases
|
||||
|
||||
To list deleted databases, include the `--show-deleted` option with your
|
||||
`influxdb3 show databases` command:
|
||||
|
||||
```sh
|
||||
influxdb3 show databases --show-deleted
|
||||
```
|
||||
|
||||
<!-- ### Output to a Parquet file
|
||||
|
||||
To output your list of databases to a Parquet file, provide the following
|
||||
options with the `influxdb3 show databases` command:
|
||||
|
||||
- `--format`: `parquet`
|
||||
- `-o`, `--output`: the filepath to the Parquet file to output to
|
||||
|
||||
```sh
|
||||
influxdb3 query \
|
||||
--format parquet \
|
||||
--output path/to/databases.parquet
|
