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
Parameter Description Required?
adapter Name of the adapter to connect to the backend. Yes
adapter-options Options specific to writing to the chosen backend, handled by the adapter. See adapter documentation

warning 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

| put value = Math.random()
| write influxdb
  -db "testdb"
  -measurement "mymetric"
