For previous review comments refer: #499

* feature/m1-docker-build-support - separate jammy and alpine - add zilla version as env var - add the docker platform to properties - don't need to use alpine for build * docker image tagging options separate alpine base image from the default image and add more tagging options * set the version env var in the alpine build * remove the suffix for local build * make version tagging more explicit for each profile * move the alpine specific builds into the docker-image module * reduce the folder complexity and add child pom placeholders * revert the docker-image pom to develop * Use buildx for multi-arch images, build alpine image for release only * Move inline assembly to descriptor file and reference from alpine image --------- Co-authored-by: John Fallows <john.r.fallows@gmail.com>

Should we introduce a ValueValidator.NOP to return from supplyValidator so we can avoid these null checks?

we already have ValueValidator no op, null check here is redundant. removed it.

I thought it was 1 byte (magic) followed by int32 (schemaId) then payload, no?
This has 6-byte prefix, not 5 bytes.

that's true, but I have added this script to mimic the scenario when the prefix can be more than five byte. So that the padding can be dynamic.

Can the json decoder below be precreated and reused instead of creating afresh each time?

this doesn't seems possible as we don't have a method to take reuse JsonDecoder.

but I was able to optimise BinaryEncoder & reuse the same instance.

We are calculating index + j more than once here and also j is not descriptive.

final int charByteLimit =. index + charByteCount; for (int charByteIndex = index + 1; charByteIndex < charByteLimit; charByteIndex++) { if (charByteIndex >= limit || (data.getByte(charByteIndex) & 0b11000000) != 0b10000000) { break validate; } }

I think the break above needs to break from the outer while loop, not just the for loop, so we'll need to add a validate: label to the while loop, agree?

+    @Override
+    public int enrich(
+        int schemaId,
+        ValueConsumer next)


What is the intention of the return value of enrich?

It seems like it is trying to say how much of the input should be ignored, while also potentially writing something to next.

So in the case of embed where we are adding the prefix bytes, the PREFIX_LENGTH would already be passed to next, so perhaps this case should return 0?

And when we are doing exclude, meaning we are stripping off the PREFIX_LENGTH bytes, we would not call next so we need to return PREFIX_LENGTH to indicate how many bytes we skipped over.

The implementation below is returning PREFIX_LENGTH for both cases, is it intentional?

+        }

Does it make sense to have booleans for embed and exclude or is this more a funciton of whether the validator is read vs write?

If it is a property of the validator, then perhaps we need to pass this context from the validator to the catalog handler, either via a parameter or by having 2 methods on catalog handler?
