the class ShardDataTree method applyReplicatedPayload.

/**
 * Apply a payload coming from the leader, which could actually be us. This method assumes the leader and follower
 * SchemaContexts match and does not perform any pruning.
 *
 * @param identifier Payload identifier as returned from RaftActor
 * @param payload Payload
 * @throws IOException when the snapshot fails to deserialize
 * @throws DataValidationFailedException when the snapshot fails to apply
 */
void applyReplicatedPayload(final Identifier identifier, final Payload payload) throws IOException, DataValidationFailedException {
    /*
         * This is a bit more involved than it needs to be due to to the fact we do not want to be touching the payload
         * if we are the leader and it has originated with us.
         *
         * The identifier will only ever be non-null when we were the leader which achieved consensus. Unfortunately,
         * though, this may not be the case anymore, as we are being called some time afterwards and we may not be
         * acting in that capacity anymore.
         *
         * In any case, we know that this is an entry coming from replication, hence we can be sure we will not observe
         * pre-Boron state -- which limits the number of options here.
