Write sink uses adapters supported by Juttle to send data points generated by the preceding Juttle flowgraph to the remote backend, usually for permanent storage. The newly written points can then be queried from the backend via
read <adapter> just like any other points in Juttle.
... | write <adapter> adapter-options
||Name of the adapter to connect to the backend.||Yes|
||Options specific to writing to the chosen backend, handled by the adapter.||See adapter documentation|
As adapters don't support operations that delete data, care must be
taken when setting up a program ending in write. We recommend always testing
your Juttle program by ending it in view table or
view text to see what data points it is
generating, and replacing those outputs with
write only when you are fully
satisfied with the result.
Example: Write random values into the InfluxDB database
emit | put value = Math.random() | write influxdb -db "testdb" -measurement "mymetric"
