Administer InfluxDB 3 Core

The following articles provide information about managing your InfluxDB 3 Core resources:

Identify InfluxDB 3 Core version

Learn how to identify your InfluxDB 3 Core version using command-line tools, HTTP endpoints, and other methods.

Manage databases

An InfluxDB 3 Core database is a named location where time series data is stored. Each database can contain multiple tables.

Manage tables

Tables in InfluxDB 3 Core are synonymous with measurements and contain time series data. Each table has a defined schema with tag and field columns.

Manage tokens

Manage tokens to authenticate and authorize access to server actions, resources, and data in an InfluxDB 3 Core instance.

Manage the Last Value Cache

The InfluxDB 3 Core Last Value Cache (LVC) lets you cache the most recent values for specific fields in a table, improving the performance of queries that return the most recent value of a field for specific time series or the last N values of a field.

Manage the Distinct Value Cache

The InfluxDB 3 Core Distinct Value Cache (DVC) lets you cache distinct values of one or more columns in a table, improving the performance of queries that return distinct tag and field values.

Query system data

Query system tables to see data related to the server, queries, and tables in an InfluxDB 3 Core instance. Use the HTTP SQL query API to retrieve information about your database server and table schemas.

Back up and restore data

Back up and restore your InfluxDB 3 Core instance by copying object storage files in the recommended order.

Performance tuning

Optimize InfluxDB 3 Core performance by tuning thread allocation, memory settings, and other configuration options for your specific workload.

Security

Tune InfluxDB 3 Core security for local requirements.

Upgrade InfluxDB 3 Core

Learn how to upgrade your InfluxDB 3 Core instance to the latest version.

Upgrade to InfluxDB 3 Enterprise

Upgrade from InfluxDB 3 Core to InfluxDB 3 Enterprise. Your existing data and plugins are compatible–no data migration is required.

Use the InfluxDB 3 MCP server

Use the InfluxDB Model Context Protocol (MCP) server to interact with and manage InfluxDB 3 Core using natural language with LLM agents to query and analyze data, manage databases and more. Query InfluxDB 3 Core documentation from your IDE using the InfluxDB documentation Model Context Protocol (MCP) server.
