Maybe this will be done as part of the journal optimization task later. This is actually not viable. Because the way we are validating holes, transaction health and other things. We move a lot around the buffer to make sure the register being read is valid, that there are not holes and other things like that. Because of that it is not possible to replace the Buffer by a streaming, as reading those files without a Buffer would be too costly. I've done a quick prototype and the reading time was prohibitive. I will try to improve how the memory is read by some other optimization. (Maybe reusing the same buffer along all the files, what is quite possible).
