Ie even if i saw a talk from facebook that says cassandra is awesome on solaris x running on cool threads chips, but if i was at a windows intel shop i might not pain myself with the burden. Cassandra uses specific native/unsafe libraries not guarenteed to be portable. Eg once i was using a non sun jvm and the saved key caches would not load. As to oracle not knowing open source, maybe not but sun had its own issues, see the story about apache harmony and sun unwilling to certify the harmony jvm. What about Micro$oft and jplus plus or how google managed to clone java and create the android playform. Leta not forget suns license which jas made it a total pita to get java ported and installed on linux amd bsds alike. That non curlable download process. -- Sorry this was sent from mobile. Will do less grammar and spell check than usual.
