objectIds is currently required by the IDeleteFeaturesOptions - this should not be the case since you can also use where clauses to delete features.

There is a couple reasons why objectIds is required. First, it's the most commonly used parameter for deleting features. Second, there's no conditional logic in typescript interfaces. Not only can you use where but you can also use geometry to delete features. And when providing geometry you are also are required to provide geometryType and possibly inSR. But one or some combination of the three has to be included to prevent a server error.

I believe you can still use where or geometry with objectIds: [] to make TS happy and still successfully delete features.

Or there would need to be extensive interface splitting to account for all possibilities of parameters that may be passed to deleteFeatures().

I recall this being brought up when the CRUD methods were added to the package but couldn't hunt down the specific comment.

Thanks all, and sorry about the delay on this. We'll merge this since setting the type to "optional" is not a breaking change, and then we'll follow-up by creating an issue to re-factor type issue holistically, taking into account some of the things that @COV-GIS mentioned:

• you can delete via a where or objectIds or geometry (or others too perhaps?)
• If you pass a geometry you also need to pass a geometry geometryType
• etc
