" With this series the mutation compactor can now consume a v2 stream. On the output side it still uses v1, so it can now act as an online v2->v1 converter. This allows us to push out v2->v1 conversion to as far as the compactor, usually the next to last component in a read pipeline, just before the final consumer. For reads this is as far as we can go, as the intra-node ABI and hence the result-sets built are v1. For compaction we could go further and eliminate conversion altogether, but this requires some further work on both the compactor and the sstable writer and so it is left to be done later. To summarize, this patchset enables a v2 input for the compactor and it updates compaction and single partition reads to use it.
