Benedict Elliott Smith commented on CASSANDRA-18355:
----------------------------------------------------
So, it would also be nice in this patch to ensure we aren't double writing the
transaction contents. We already persist any constant write values in the
transaction, and don't need them to reconstruct their portion of the `Writes` -
which for most cases will be the vast majority of a `Writes`.
So, really, instead of `Writes` we should be persisting only what we read from
replicas that are necessary for computing the `Writes` from the local
`PartialTxn`. Does that make sense?
