The sink will publish the result into a InfluxDB V2.X
.
Connection properties:
Property name | Optional | Description |
---|---|---|
addr | false | The addr of the InfluxDB |
token | true | The token of access InfluxDB |
org | false | The InfluxDB organization |
bucket | false | The InfluxDB bucket |
certificationPath | true | The certification path. It can be an absolute path, or a relative path. If it is an relative path, then the base path is where you executing the kuiperd command. For example, if you run bin/kuiperd from /var/kuiper , then the base path is /var/kuiper ; If you run ./kuiperd from /var/kuiper/bin , then the base path is /var/kuiper/bin . |
privateKeyPath | true | The private key path. It can be either absolute path, or relative path, which is similar to use of certificationPath. |
rootCaPath | true | The location of root ca path. It can be an absolute path, or a relative path, which is similar to use of certificationPath. |
tlsMinVersion | true | Specifies the minimum version of the TLS protocol that will be negotiated with the client. Accept values are tls1.0 , tls1.1 , tls1.2 and tls1.3 . Default: tls1.2 . |
renegotiationSupport | true | Determines how and when the client handles server-initiated renegotiation requests. Support never , once or freely options. Default: never . |
insecureSkipVerify | true | If InsecureSkipVerify is true , TLS accepts any certificate presented by the server and any host name in that certificate. In this mode, TLS is susceptible to man-in-the-middle attacks. The default value is false . The configuration item can only be used with TLS connections. |
Write options:
Property name | Optional | Description |
---|---|---|
measurement | false | The measurement of the InfluxDb (like table name) |
tags | true | The tags to write, the format is like {"tag1":"value1"}. The value can be dataTemplate format, like {"tag1":"{{.temperature}}"} |
fields | true | The fields to write, the format is like ["field1", "field2"]. If fields is not set, all fields selected in the SQL will all written to InfluxDB. |
precision | true | The precision of the timestamp. Support ns , us , ms , s . Default: ms . |
tsFieldName | true | The field name of the timestamp. If set, the written timestamp will use the value of the field. For example, if the data has {"ts": 1888888888} and the tsFieldName is set to ts, then the value 1888888888 will be used when written to InfluxDB. Make sure the value is formatted according to the precision. If not set, the current timestamp will be used. |
useLineProtocol | true | Use line protocol format or not. Default is false. If line protocol is set, the dataTemplate must format to the line protocol format. |
Other common sink properties including batch settings are supported. Please refer to the sink common properties for more information.
Below is a sample for selecting temperature greater than 50 degree and write into influxDB.
