## InfluxDB
InfluxDB as storage since SkyWalking 7.0. It depends on `H2/MySQL` storage-plugin to store `metadata` like `Inventory` and `ProfileTask`. So, when we set `InfluxDB` as storage provider. We need to configure properties of InfluxDB and Metabase.
```yaml
storage:
influx:
# Metadata storage provider configuration
metabaseType:${SW_STORAGE_METABASE_TYPE:H2}# There are 2 options as Metabase provider, H2 or MySQL.
actions:${SW_STORAGE_INFLUXDB_ACTIONS:1000}# the number of actions to collect
duration:${SW_STORAGE_INFLUXDB_DURATION:1000}# the time to wait at most (milliseconds)
fetchTaskLogMaxSize:${SW_STORAGE_INFLUXDB_FETCH_TASK_LOG_MAX_SIZE:5000}# the max number of fetch task log in a request
```
All connection related settings including link url, username and password are in `application.yml`. The Metadata storage provider settings can refer to the configuration of **H2/MySQL** above.
## ElasticSearch 5
ElasticSearch 5 is incompatible with ElasticSearch 6 Java client jar, so it could not be included in native distribution.
[OpenSkyWalking/SkyWalking-With-Es5x-Storage](https://github.com/OpenSkywalking/SkyWalking-With-Es5x-Storage) repo includes the distribution version.
