+An {{< product-name >}} database is a named location where time series data is
+stored. Each database can contain multiple tables.
+
+> [!Note]
+> **If coming from InfluxDB v1**, the concepts of databases and retention policies
+> have been combined into a single concept--database. Retention policies are no
+> longer part of the InfluxDB data model.
+> However, {{% product-name %}} does
+> support InfluxQL, which requires databases and retention policies.
+> See [InfluxQL DBRP naming convention](/influxdb3/version/admin/databases/create/#influxql-dbrp-naming-convention).

+> **If coming from InfluxDB v2, InfluxDB Cloud (TSM), or InfluxDB Cloud Serverless**,
+> _database_ and _bucket_ are synonymous.
+
+<!--
+## 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.
