Hi,
my app that uses cayenne got few rows changed externally in mysql
database. I observed that app didn't behave according to these changes
and after restarting it worked as expected (with those changed rows).
Could this be due to cayenne caching mechanism. Or is it probably bug on
my side? If former, is it possible to set time expiration on cache, or
invoke expiration manually?
Thanks,
Regards,
Marek

Well, guess what, the first instance where I absolutely need inheritance does
require horizontal modeling. Two legacy tables happen to have a very similar
column structure and server very similar purposes, and since the processing is
complicated and accesses many fields of each record, having a common superclass
wired up would really simplify a lot of code.
So the question is: Is there any realistic hope that this will be done soon?
Would outside help speed up things?
Limited help, unfortunately. I'll have to justify any time I sink into this :-(
The other approach might be faking a vertical/joined scenario using views.
However, I'd like to avoid that because I know that views tend to come with
their own cans of worms (updateability and lack of useful metadata).
