Kodo typically retains the default transaction isolation level
of the JDBC driver. However, you can specify a transaction isolation
level to use through the
kodo.jdbc.TransactionIsolation configuration
property. The following is a list of standard isolation levels.
Note that not all databases support all isolation levels.
default: Use the JDBC driver's default
isolation level. Kodo uses this option if you do not
explicitly specify any other.
none: No transaction isolation.
read-committed: Dirty reads are
prevented; non-repeatable reads and phantom reads can
occur.
read-uncommitted: Dirty reads,
non-repeatable reads and phantom reads can occur.
repeatable-read: Dirty reads and
non-repeatable reads are prevented; phantom reads can occur.
serializable: Dirty reads,
non-repeatable reads, and phantom reads are prevented.
