+ * Session handler using a PDO connection to read and write data.

+ * different locking strategies to handle concurrent access to the same session.
+ * Locking is necessary to prevent loss of data due to race conditions and to keep
+ * the session data consistent between read() and write(). With locking, requests
+ * for the same session will wait until the other one finished writing. For this
+ * reason it's best practice to close a session as early as possible to improve
+ * concurrency. PHPs internal files session handler also implements locking.
+ *
+ * Attention: Since SQLite does not support row level locks but locks the whole database,
+ * it means only one session can be accessed at a time. Even different sessions would wait
+ * for another to finish. So saving session in SQLite should only be considered for
+ * development or prototypes.
+ *
+ * Session data is a binary string that can contain non-printable characters like the null byte.
+ * For this reason it must be saved in a binary column in the database like BLOB in MySQL.
+ * Saving it in a character column could corrupt the data. You can use createTable()
+ * to initialize a correctly defined table.
