Custom data feeds samples and documentation

[MarcBateEA]

I downloaded the Enterprise SDK v11.1 and only found the command line utility for creating the custom data feeds nodejs project, however, the documentation seems to be from an older version maybe even 10.9.1, and no documentation on custom data feeds, and no samples.

Where are the samples? I don't see them on github either, and the online documentation for the SDK doesn't have anything on custom data feeds either.

You don't have to code anything related to that. It is handled by that nodejs app that the cli tool creates, not your provider

Does your getData function re-execute once your ttl time has expired? I have added in the createKey function, but even after the ttl period, I can't get the getData function to execute once again. Not exactly sure what I am missing. 

[MarcBateEA]

yes

Thanks @MarcBateEA! Just one quick question - the ttl field should be in seconds, right? I saw that you used the setDate method which returns a timestamp in milliseconds - shouldn't you divide by 1000?

Hi,

it seems that caching in the custom data provider is not working at all in version 11.1.

Should be fixed in version 11.2: https://support.esri.com/en-us/bug/the-ttl-property-set-in-the-custom-data-provider-source-bug-00015...

Hopefully the documentation will be expanded with debugging, logging, caching and other useful details for implementing your own data providers.

Thanks for the info. I really would like the CDFs to perform better with the filter manager so the layers can be used with WAB or ExB filter widgets just like a real feature class. The way the filter widget calls the service is too slow for us to use in production environment.

If the custom data feed layer is supposed to be just like other feature layers, we want to be able to index its fields so parts of the platform like filter and queries perform the same, and don't take so long you can't use this new technology. 😉.

Hi I've tried following this guide : https://developers.arcgis.com/enterprise-sdk/guide/custom-data-feeds/create-a-yelp-custom-data-feed/... and successfully published the yelp data. I have 2 questions. 

1. Is there any way we can get more than 20 feature data? I know by default yelp only provide 20 data for the API. 

2. Is there any other sample that is accessible? I'm trying to do a demo for the twitter data but couldn't find any related documentation.

Any update is appreciated.

Thanks.
