[simplestore] what Exceptions do we need?
Hi Juozas, all,
I want to add some Exceptions to the simplestore. Juozas
you proposed following two:
- ServiceNotAvailableException
for what?
- NotFoundException
maybe:
- KeyNotUniqueException
- KeyNotFoundException
is usefull too.
Your comments?

A Exception seems to be cleaner in this case. What do you think.

Yep.

Hi,
1."ServiceNotAvailableException" is useful to handle fatal erros, "Log
message,send SNS for admin .... "
2."NotFoundException" <==> "KeyNotFoundException" is useful to optimize
"get" without "contais" and for null result, nul is also "good" value.
3."KeyNotUniqueException" <==> "DublicateKeyException" is usefull for
"put", because it returns "void" and store can be used without "contais".
all of them not useful for memory stores, because they use Map for internal
optimizations and in case "ServiceNotAvailableException" it impossible to
handle, handling will fail :)
But for stores like "JDBCStore", "FileStore", "RemoteStore" exceptions are
very useful.
