/*!# ORM Statistics
The `Statistics` singleton is used to gather the statistical information from
various code points inside Circumflex ORM. Most methods rely on non-blocking
counters from `java.util.concurrent.atomic` package.
Following statistical data is available:
* `connectionsOpened` -- the amount of physical JDBC connections opened by
`Transaction` objects;
* `connectionsClosed` -- the amount of physical JDBC connections closed by
`Transaction` objects;
* `executions` -- the total amount of invokations of the `execute` method of
`Transaction` objects
* `executionsSucceeded` -- the amount of successful invokations of the
`execute` method of `Transaction` objects;
* `executionsFailed` -- the amount of failed invokations of the `execute`
method of `Transaction` objects;
* `recordCacheHits` -- the amount of records successfully retrieved from cache;
* `recordCacheMisses` -- the amount of records retrieved from database and stored
in cache;
* `inverseCacheHits` -- the amount of inverse associations retrieved from cache;
* `inverseCacheMisses` -- the amount of inverse associations retrieved from database
and stored in cache;
* `heaviestSqlTime` -- the time (in milliseconds) of the heaviest SQL query execution;
* `heaviestSql` -- the SQL statement of the heaviest data-retrieval query.
