1) Do you get a new connection from the pool for each seaside request?
If so, how do you deal with references to objects that stick around
between requests? If not, how does the pooling work?
2) This idea has come up before but I'm curious what your take on it
is these days: would it help to have a single shared connection that
was used most of the time, and had a very large cache but never any
commits, and then switch to a pooled, small-cache transaction whenever
you need to do writes? I'm picturing an interface something like
connection root allItems do:
html anchor callback: [self delete: ea]; text: 'Delete']
connection writeConnectionFor: anItem do:
[:write :item |
write root allItems remove: item ifAbsent: .
