> Right now, binary row manipulations lead to garbage byte[] instances, because schema version is prepended as 4 bytes in the beginning of the array. This is absolutely unnecessary and there are no benefits to such approach.
> Methods `org.apache.ignite.internal.schema.BinaryRow#bytes` / `org.apache.ignite.internal.schema.BinaryRow#byteBuffer` are a part of a very old design, we should revisit them, and hopefully remove them. This will affect serialization, but it's worth it imo.
