-- Creates a new session. A session can be used to perform transactions
-- that read and\/or modify data in a Cloud Spanner database. Sessions are
-- meant to be reused for many consecutive transactions. Sessions can only
-- execute one transaction at a time. To execute multiple concurrent
-- read-write\/write-only transactions, create multiple sessions. Note that
-- standalone reads and queries use a transaction internally, and count
-- toward the one transaction limit. Cloud Spanner limits the number of
-- sessions that can exist at any given time; thus, it is a good idea to
-- delete idle and\/or unneeded sessions. Aside from explicit deletes,
-- Cloud Spanner can delete sessions for which no operations are sent for
-- more than an hour. If a session is deleted, requests to it return
-- \`NOT_FOUND\`. Idle sessions can be kept alive by sending a trivial SQL
-- query periodically, e.g., \`\"SELECT 1\"\`.
