Chapter 164. InfluxDB Component
Available as of Camel version 2.18
This component allows you to interact with InfluxDB https://influxdata.com/time-series-platform/influxdb/ a time series database. The native body type for this component is Point (the native influxdb class), but it can also accept Map<String, Object> as message body and it will get converted to Point.class, please note that the map must contain an element with InfluxDbConstants.MEASUREMENT_NAME as key.
Aditionally of course you may register your own Converters to your data type to Point, or use the (un)marshalling tools provided by camel.
From Camel 2.18 onwards Influxdb requires Java 8.
Maven users will need to add the following dependency to their pom.xml for this component:
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-influxdb</artifactId>
<version>x.x.x</version>
<!-- use the same version as your Camel core version -->
</dependency>164.1. URI format
