> LLAP uses a completely separate read path in ORC to allow for caching and 
> parallelization of reads and processing. This path does not support ACID. As 
> far as I remember ACID logic is embedded inside ORC format; we need to 
> refactor it to be on top of some interface, if practical; or just port it to 
> LLAP read path.
> Another consideration is how the logic will work with cache. The cache is 
> currently low-level (CB-level in ORC), so we could just use it to read bases 
> and deltas (deltas should be cached with higher priority) and merge as usual. 
> We could also cache merged representation in future.
