Optional. If true, specifies a multiplexed session. A multiplexed session
may be used for multiple, concurrent read-only operations but can not be
used for read-write transactions, partitioned reads, or partitioned
queries. Multiplexed sessions can be created via
[CreateSession][google.spanner.v1.Spanner.CreateSession] but not via
[BatchCreateSessions][google.spanner.v1.Spanner.BatchCreateSessions].
Multiplexed sessions may not be deleted nor listed.
