Hi, Say we have a page of 4 elements that are "DELTA_LENGTH_BYTE_ARRAY" and we would like to create 2 arrays of 2 elements each in a streaming fashion.
I can't find a process over which we can do this without first reading all the encoded lengths. This is because I have been unable to find a way to identify where the "values" part starts. Using the example in the spec [1]: DeltaEncoding(5, 5, 6, 6) "HelloWorldFoobarABCDEF" say they are encoded as bytes as `[a,b,c,d,e, ...]["H", "e", ...]`. How can we find the position between ] and [?
