To answer your underlying question though: **JsonProperty** `@JsonProperty` is all about how this request body is serialized/deserialized by Jackson. If you give the annotation a value, Jackson uses that as the property name when serializing/deserializing. If no value is given, the name of the instance variable is used by default. (Since the constant `NUM_SLICES` has the value `"numShards"` and matches the variable name, I probably should've not specified any value here - I think this was a copy/paste oversight.) **Schema** The `@Schema` annotation otoh is all about metadata. It lets you provide descriptions, additional references, alternate names, etc. into the generated OpenAPI Spec ("OAS"), and therefore into the client code that's generated from that OAS. The `name` property that we're using here lets you associate an identifier with the field in question. So mostly you'll see `@Schema(name=...` when the name of a property in the OAS should be different than the field name Jackson uses to serialize it. (This is important from a good-docs perspective sometimes, but it's also something our Java-code-generation template relies on periodically) There's no reason to use `@Schema` here, since the variable name and both annotations all work out to the literal `"numShards"` - so I'll remove it. Not sure how this got here: maybe I started to add a description before getting distracted? In any case, I appreciate you flagging it. ---- > I feel the "slices" nomenclature is an unfortunate one that we should get away from, at least on the API surface. Idk whether I like "slices" or not, but I'll remove it here. -- This is an automated message from the Apache Git Service.
