public static enum IPreparedStatementCache.ReuseProbability
extends Enum<IPreparedStatementCache.ReuseProbability>
An enum for the degree of probability to which a prepared statement is reused later on. This is used for managing
the cache of prepared statements so that statements which are more likely reused are kept in the cache longer. Rule
of thumb:
- For global statements which are used regularly (such as lookup object in cdo_objects) use
MAX. - For constant object-specific statements which are used regularly use
HIGH. - For object-specific statements which are assembled from constants which are used regularly use
MEDIUM. - For all other dynamic statements, like queries, use
LOW
