InfluxDB 3 Enterprise configuration options
InfluxDB 3 Enterprise lets you customize your configuration by using
influxdb3 command options or by setting environment variables.
Configure your server
Pass configuration options using either command options or environment variables. Command options take precedence over environment variables.
Global vs serve-specific options
Some options are global (specified before the command) while others are serve-specific (specified after serve):
- Global options: Apply to the
influxdb3CLI itself (for example,--num-io-threads) - Serve options: Apply only to the
servecommand (for example,--node-id,--object-store,--verbose)
Example command with global and serve-specific options
influxdb3 --num-io-threads=4 serve \
--node-id node0 \
--cluster-id cluster0 \
--license-email example@email.com \
--object-store file \
--data-dir ~/.influxdb3 \
--verbose \
--log-filter infoExample environment variables
export INFLUXDB3_ENTERPRISE_LICENSE_EMAIL=example@email.com
export INFLUXDB3_ENTERPRISE_CLUSTER_ID=cluster0
export INFLUXDB3_NODE_IDENTIFIER_PREFIX=my-node
export INFLUXDB3_OBJECT_STORE=file
export INFLUXDB3_DB_DIR=~/.influxdb3
export LOG_FILTER=info
influxdb3 serveGlobal configuration options
The following options apply to the influxdb3 CLI globally and must be specified before any subcommand (for example, serve):
num-io-threads
Sets the number of threads allocated to the IO runtime thread pool. IO threads handle HTTP request serving, line protocol parsing, and file operations.
--num-io-threads is a global option that must be specified before the serve command.
Default: 2
# Set IO threads (global option before serve)
influxdb3 --num-io-threads=8 serve --node-id=node0 --object-store=fileFor detailed information about thread allocation, see the Resource Limits section.
| influxdb3 option | Environment variable |
|---|---|
--num-io-threads | INFLUXDB3_NUM_IO_THREADS |
Server configuration options
General
cluster-id
Specifies the cluster identifier that prefixes the object store path for the Enterprise Catalog.
This value must be different than the --node-id value.
| influxdb3 serve option | Environment variable |
|---|---|
--cluster-id | INFLUXDB3_ENTERPRISE_CLUSTER_ID |
data-dir
For the file object store, defines the location InfluxDB 3 Enterprise uses to store files locally.
Required when using the file object store.
| influxdb3 serve option | Environment variable |
|---|---|
--data-dir | INFLUXDB3_DB_DIR |
mode
Sets the mode to start the server in, allowing you to create specialized nodes in a distributed cluster.
This option supports the following values:
all(default): Enables all server modesingest: Enables only data ingest capabilitiesquery: Enables only query capabilitiescompact: Enables only compaction processesprocess: Enables only data processing capabilities
You can specify multiple modes using a comma-delimited list (for example, ingest,query).
Default: all
Thread allocation for different modes:
Ingest mode: Benefits from additional IO threads for line protocol parsing. For high-throughput scenarios with multiple concurrent writers, consider increasing
--num-io-threads(global option) to 8-16+ to optimize performance. DataFusion threads are still needed for snapshot operations.Query mode: Benefits from maximizing DataFusion threads. Use most available cores for DataFusion with minimal IO threads (2-4).
Compact mode: Primarily uses DataFusion threads for sort/dedupe operations.
All mode: Requires balanced thread allocation based on your workload mix.
Example configurations:
# High-throughput ingest node (32 cores)
influxdb3 --num-io-threads=12 serve --mode=ingest --datafusion-num-threads=20
# Query-optimized node (32 cores)
influxdb3 --num-io-threads=4 serve --mode=query --datafusion-num-threads=28
# Balanced all-in-one (32 cores)
influxdb3 --num-io-threads=6 serve --mode=all --datafusion-num-threads=26| influxdb3 serve option | Environment variable |
|---|---|
--mode | INFLUXDB3_ENTERPRISE_MODE |
node-id
Specifies the node identifier used as a prefix in all object store file paths. This should be unique for any hosts sharing the same object store configurationโfor example, the same bucket.
| influxdb3 serve option | Environment variable |
|---|---|
--node-id | INFLUXDB3_NODE_IDENTIFIER_PREFIX |
node-id-from-env
Specifies the node identifier used as a prefix in all object store file paths.
Takes the name of an environment variable as an argument and uses the value of that environment variable as the node identifier.
This option cannot be used with the --node-id option.
| influxdb3 serve option | Environment variable |
|---|---|
--node-id-from-env | INFLUXDB3_NODE_IDENTIFIER_FROM_ENV |
Example using โnode-id-from-env
export DATABASE_NODE=node0 && influxdb3 serve \
--node-id-from-env DATABASE_NODE \
--cluster-id cluster0 \

# Generate an admin token offline
influxdb3 create token \

--permission "db:db1,db2:read,write" \
--permission "db:db3:read" \

plugin-repo
Specifies the base URL of the remote repository used when referencing plugins with the gh: prefix.
When you create a trigger with a plugin filename starting with gh:, InfluxDB fetches
the plugin code from this repository URL.
The URL construction automatically handles trailing slashesโboth formats work identically:
https://example.com/plugins/(with trailing slash)https://example.com/plugins(without trailing slash)
Default: The official InfluxDB 3 plugins repository at https://raw.githubusercontent.com/influxdata/influxdb3_plugins/main/
| influxdb3 serve option | Environment variable |
|---|---|

Example usage
# Use a custom organization repository
influxdb3 serve \
--plugin-dir ~/.plugins \
--plugin-repo "https://raw.githubusercontent.com/myorg/influxdb-plugins/main/"
# Use an internal mirror
influxdb3 serve \
--plugin-dir ~/.plugins \
--plugin-repo "https://internal.company.com/influxdb-plugins/"
# Set via environment variable
export INFLUXDB3_PLUGIN_REPO="https://custom-repo.example.com/plugins/"
influxdb3 serve --plugin-dir ~/.pluginsvirtual-env-location

|---|---|
--catalog-sync-interval | INFLUXDB3_ENTERPRISE_CATALOG_SYNC_INTERVAL |
wait-for-running-ingestor
Specifies how long to wait for a running ingestor during startup.
Default: 10s
| influxdb3 serve option | Environment variable |
|---|---|
--wait-for-running-ingestor | INFLUXDB3_ENTERPRISE_WAIT_FOR_RUNNING_INGESTOR |
Resource Limits
num-cores
Limits the number of CPU cores that the InfluxDB 3 Enterprise process can use when running on systems where resources are shared.
Default: All available cores on the system
Maximum cores allowed is determined by your InfluxDB 3 Enterprise license:
- Trial: up to 256 cores
- At-Home: 2 cores
- Commercial: per contract
When specified, InfluxDB automatically assigns the number of DataFusion threads and IO threads based on the core count.
Default thread assignment logic when num-cores is set:
- 1-2 cores: 1 IO thread, 1 DataFusion thread
- 3 cores: 1 IO thread, 2 DataFusion threads
- 4+ cores: 2 IO threads, (n-2) DataFusion threads
This automatic allocation applies when you donโt explicitly set --num-io-threads and --datafusion-num-threads.
You can override the automatic thread assignment by explicitly setting --num-io-threads
and --datafusion-num-threads.
This is particularly important for specialized
workloads like ingest mode where you may need more IO threads than the default allocation.
Constraints:
- Must be at least 2
- Cannot exceed the number of cores available on the system
- Total thread count from
--num-io-threads(global option) and--datafusion-num-threadscannot exceed thenum-coresvalue
| influxdb3 serve option | Environment variable |
|---|---|
--num-cores | INFLUXDB3_ENTERPRISE_NUM_CORES |
datafusion-num-threads
Sets the number of threads allocated to the DataFusion runtime thread pool. DataFusion threads handle:
- Query execution and processing
- Data aggregation and transformation
- Snapshot creation (sort/dedupe operations)
- Parquet file generation
Default:
- If not specified and
--num-coresis not set: All available cores minus IO threads - If not specified and
--num-coresis set: Automatically determined based on core count (see--num-cores)
DataFusion threads are used for both query processing and snapshot operations. Even ingest-only nodes use DataFusion threads during WAL snapshot creation.
Constraints: When used with --num-cores, the sum of --num-io-threads and --datafusion-num-threads cannot exceed the num-cores value
| influxdb3 serve option | Environment variable |
|---|---|
--datafusion-num-threads | INFLUXDB3_DATAFUSION_NUM_THREADS |
