While running through a piece of code for performance tuning, i noticed that the pooled database connection is not used immediately, it follows some pre-processing before the connection used to delegate a SQL update call.
I fixed the codes by delaying the retrieval of the pooled database connection until before the codes is ready to call on the insert method.
As i am trying to update the documentation that this optimization is done, how should i work it in a sentence or title?
Old Codes:
...
connection = ConnectionFactory.getPooledConnection(); // get pooled connection
String message = StringUtils.replace(log, "a", "b");
// many other processing
connection.update(message);
connection.release();
...
New Codes:
...
String message = StringUtils.replace(log, "a", "b");
// many other processing
connection = ConnectionFactory.getPooledConnection(); // get pooled connection
connection.update(message);
connection.release();
...
Not sure this case actually warrants it – because you’ve made the code behave more like it “should”. But generally, such deferral of work until the moment it is needed is referred to as “lazy initialization”.
