Customize your InfluxDB configuration by using [`influxd`](/influxdb/v2.0/reference/cli/influxd/)
configuration flags, setting environment variables, or defining configuration
options in a configuration file.
### Configuration precedence
InfluxDB honors configuration settings using the following precedence:
1. `influxd` flags
2. Environment variables
3. Configuration file settings
### InfluxDB configuration file
When `influxd` starts, it checks for a file named `config.*` **in the current working directory**.
The file extension depends on the syntax of the configuration file.
InfluxDB configuration files support the following syntaxes:
- **YAML** (`.yaml`, `.yml`)
- **TOML** (`.toml`)
- **JSON** (`.json`)
To customize the directory path of the configuration file, set the `INFLUXD_CONFIG_PATH`
environment variable to your custom path.
```sh
export INFLUXD_CONFIG_PATH=/path/to/custom/config/directory
```
On startup, `influxd` will check for a `config.*` in the `INFLUXD_CONFIG_PATH` directory.
##### Example configuration file
{{< code-tabs-wrapper >}}
{{% code-tabs %}}
[YAML](#)
[TOML](#)
[JSON](#)
{{% /code-tabs %}}
{{% code-tab-content %}}
```yaml
query-concurrency: 20
query-queue-size: 15
secret-store: vault
session-length: 120
tls-cert: /path/to/influxdb.crt
tls-key: /path/to/influxdb.key
```
{{% /code-tab-content %}}
{{% code-tab-content %}}
```toml
query-concurrency = 20
query-queue-size = 15

tls-key = "/path/to/influxdb.key"
```
{{% /code-tab-content %}}
{{% code-tab-content %}}
```json

"tls-key": "/path/to/influxdb.key"
}
```
{{% /code-tab-content %}}
{{< /code-tabs-wrapper >}}

Only non-default settings need to be defined in the configuration file.

### http-read-timeout
Maximum duration the server should try to read the entirety of new requests.

#### Set timeouts specific to your workload
Although no `http-read-timeout` is set by default, we **strongly recommend**
setting a timeout specific to your workload.
HTTP timeouts protect against large amounts of open connections that could
potentially hurt performance.

### storage-series-id-set-cache-size
Size of the internal cache used in the TSI index to store
previously calculated series results.
Cached results are returned quickly rather than needing to be recalculated when
a subsequent query with the same tag key-value predicate is executed.
Setting this value to `0` will disable the cache and may decrease query performance.
**Default:** `100`
{{% note %}}
This value should only be increased if the set of regularly used tag key-value
predicates across all measurements for a database is larger than 100.
An increase in cache size may lead to an increase in heap usage.

### store
Specifies the data store for REST resources.

`memory` is meant for transient environments, such as testing environments, where
data persistence does not matter.
InfluxData does not recommend using `memory` in production.
