InfluxDB file system layout

The InfluxDB Enterprise file system layout depends on the installation method or containerization platform used to install InfluxDB Enterprise.

InfluxDB Enterprise file structure

The InfluxDB file structure includes the following:

Data directory

(Data nodes only) Directory path where InfluxDB Enterprise stores time series data (TSM files). To customize this path, use the [data].dir configuration option.

WAL directory

(Data nodes only) Directory path where InfluxDB Enterprise stores Write Ahead Log (WAL) files. To customize this path, use the [data].wal-dir configuration option.

Hinted handoff directory

(Data nodes only) Directory path where hinted handoff (HH) queues are stored. To customize this path, use the [hinted-handoff].dir configuration option.

Metastore directory

Directory path of the InfluxDB Enterprise metastore, which stores information about the cluster, users, databases, retention policies, shards, and continuous queries.

On data nodes, the metastore contains information about InfluxDB Enterprise meta nodes. To customize this path, use the [meta].dir configuration option in your data node configuration file.

On meta nodes, the metastore contains information about the InfluxDB Enterprise RAFT cluster. To customize this path, use the [meta].dir configuration option in your meta node configuration file.

InfluxDB Enterprise configuration files

InfluxDB Enterprise stores default data and meta node configuration file on disk. For more information about using InfluxDB Enterprise configuration files, see:

File system layout

InfluxDB Enterprise supports .deb- and .rpm-based Linux package managers. The file system layout is the same with each.

Directory permissions

The user running the influxd process should have the following permissions for directories in the InfluxDB file system:

Directory pathPermission
.../influxdb/755
.../influxdb/data/755
.../influxdb/hh/700
.../influxdb/meta/755
.../influxdb/wal/700

The future of Flux

Flux is going into maintenance mode. You can continue using it as you currently are without any changes to your code.

Flux is going into maintenance mode and will not be supported in InfluxDB 3.0. This was a decision based on the broad demand for SQL and the continued growth and adoption of InfluxQL. We are continuing to support Flux for users in 1.x and 2.x so you can continue using it with no changes to your code. If you are interested in transitioning to InfluxDB 3.0 and want to future-proof your code, we suggest using InfluxQL.
