-----------------------------------------
Matt, could you please confirm that it indeed increases the performance?
> CMP Issues two selects for each CMP bean read operation

> Key: GERONIMO-2074
> URL: http://issues.apache.org/jira/browse/GERONIMO-2074
> Project: Geronimo
> Type: Bug
> Security: public(Regular issues)
> Reporter: Matt Hogstrom
> Assignee: Gianny Damour
> Fix For: 1.2
> Attachments: GERONIMO-2074.patch
>
> Number of executions = 84422
> Statement text = SELECT Q.symbol, Q.low, Q.open1, Q.volume, Q.price,
Q.high, Q.companyName, Q.change1 FROM QuoteEJB Q WHERE Q.symbol = ?
> Number of executions = 84464
> Statement text = SELECT Q.symbol FROM QuoteEJB Q WHERE Q.symbol
= ?
> This is running the PrimitiveServlet2EntityLocal. In this primitive a CMP Entity bean
is selected and all fields referenced. Performance would be greatly improved if we only did
the full select and avoided the round trip of two queries.
> The difference in counts is beause of a bug I'm chasing with Jencks re: some Tx failing.
