      Description

      When reconstructing a prepared transaction during replication recovery, we try to timestamp a multikey write with a timestamp from the LogicalClock. The LogicalClock may not have been initialized yet, though, which leads to an error if we try to timestamp the write with a zero timestamp. A proposed solution is to instead propagate the prepare timestamp of the transaction into that codepath so that we can timestamp the write with the transaction's prepare timestamp.
