Hello community,
i am working on custom component.
This component requires specific input schema and produce 1 row as result.
Like tREST component i have already seen components, that setup specific output schema
By documentation of Talend Component Kit i have found some examples for DiscoverSchema and Records, but at the end it has never ended in own definition of schema for component.
Is there any (clear) guide to provide own (input/output) schema for own component?
How to make schema properties not changeable?
Is there some downloadable example for this use case?
Thanks
Anatoli
i have already seen the similar question https://community.talend.com/s/question/0D53p00008K2F2uCAF/readonly-processor-schema-andor-appending-output-schema
but provided suggestion gave no any positive influence to find a solution.
What i am lookiing for is to give any kind of information, what the user needs to provide to my component (input schema) and how he can retrieve the result (output schema)
What i have found till now by myself:
1.
Please make somewhere in kit documentation in big letters:
"After each deployment you need to restart studio"
Accessing of metadata as by https://talend.github.io/component-runtime/main/1.60.0/studio-schema.html
works without any more logic there, but only after restart of studio.
Lost some days for this...
2.
How to use DiscoverProcessorSchema for Processor with providing to user information, what parameters are for input, and what for Output? Instead of providing whole set on parameters...
3.
Still no idea how to make parameters not changeable..
Any idea ?
Need really help for it.
such thing should not be so complicated...
is one of main parts of talend.
