Parsing the data after being processed by functions

[tansuozhe123]

The result of the source data processed by the function will wrap a layer,
for example：
Raw data:{"key":"value"}
select parse(*) from mqtt;
The processed data {parse:{"key":"value1"}}, how to remove the new layer?

Use sink property dataField, set dataField=parse

[tansuozhe123]

Can we fetch the next level of data?
For example:
Data :{message:{"value":{"k":"v"}}} To get the innermost {"k":"v"}, how is the dataField parameter set,dataField =message.value?

You can use dataTemplate for complex scenario.
