Contains a reference to a BatchTransactionId and a Partition. The combination of
these two are needed to execute a partition of a partitioned query on a Connection. A
PartitionId can safely be given to a different connection and/or host to be executed
there.
A string-encoded version of this PartitionId. This encoded version can be sent
to any other Connection to be executed there, including connections on different
hosts than the current host.
