Subject Re: Child Contexts
Date Tue, 21 Sep 2010 18:38:18 GMT
Contexts and connections are more or less independent.  There is a pool of connections; there
are one or more contexts.  When a context needs a connection, eg, to write to or read from
teh database, it checks one out from the pool, and returns it to the pool as soon as it is
finished with the connection.

So a child context will share a connection with the parent in the same sense that any data
context "shares" a connection with any other context: via the shared connection pool.

In general, for a child context, /writes/ to the database will be flushed through to the parent,
and therefore performed on the parent-context level.  That's not the case for read operations.
