OpenJPA generates SQL SELECT statements to fetch database records and populates the persistent entity states
from the result data. Under certain assumptions, these select statements are invariant for an entity
or its relations except that their binding parameters vary between executions. In version 2.2.0, OpenJPA
allows these select statements be reused. Such reuse avoids the cost of regenerating these statements in
every execution.

This facility can be activated by <programlisting>openjpa.jdbc.CachesSelect</programlisting> configuration

The property value can be changed once and only once.

<para>
The assumption that a select statement for a persistent entity is invariant holds only if the fetch plan
is not dynamically modified. OpenJPA runtime currently makes no attempt to ensure that the assumption
is held true i.e. the application is not modifying the fetch plan dynamically.
