Witold, thanks for the update. I haven't yet talked to our main database
developer, but on first glance it looks like ULTM would be great for
us!! Let me clarify a few things.
Our code has an application that creates a jOOQ Configuration from a
data source:
final org.jooq.Configuration jooqConfiguration = new
DefaultConfiguration()
.set(datasource).set(SQLDialect.POSTGRES).set(new
Settings().withExecuteLogging(true));
We store this jOOQ Configuration in e.g. some DI container. In all the
manager layer, we access jOOQ like this:
return DSL.using(getConfiguration());
We therefore have one jOOQ Configuration (created from a single data
source) for the entire application, and when we need to do database
access we create a DSLContext on the fly from the configuration. I
frankly don't know the details of how jOOQ then creates JDBC connections
under the hood; this is not my area of expertise.
So with ULTM, would we create one TxManager (also from the data source)
at the same level as the jOOQ Configuration, and make it available via
the DI container? If we create multiple jOOQ DSLContexts on the fly from
the jOOQ Configuration, how does that interact with ULTM?
Let's further suppose that I have a CarManager and a WheelManager.
Storing a Car using CarManager.storeCar() would I assume use TxManager
to wrap the logic in a transaction. But inside that logic it calls
WheelManager.storeWheel() four times. Does WheelManager simply do its
work without worrying about transactions? Do I need to pass the
TxManager to WheelManager? Will the DSLContext create a new connection
that isn't part of the same transaction? Do I need to pass the
DSLContext to WheelManager? Do I need to pass the JDBC connection to
WheelManager? Or is TXManager somehow managing all this under the hood?
I'm sure if I had more SQL expertise the answers to some of these
questions might be obvious. Thanks in advance for your help.
