  - DB_MAX_CACHED_STATEMENTS_PER_CONNECTION
```
public static final String DB_MAX_CACHED_STATEMENTS_PER_CONNECTION
```
    The maximum number of prepared statements that will be cached per connection in the pool. Depending upon your JDBC Driver this may significantly help performance, or may slightly hinder performance. Default is 120, as Quartz uses over 100 unique statements. 0 disables the feature.
