Re: How is Cassandra being used?

+1 for a separate jar (and a second download link that doesn't include this jar, though I would make the primary link include it with BIG BOLD PRINT saying it is in there) +1 for a config option to turn off auto-post (defaulted on in the download that has the jar) +1 for a nodetool command to du

Sounds like the consensus is that if this is a good idea at all, it needs to be opt-in. Like I said earlier, I can live with that. On Wed, Nov 16, 2011 at 10:35 AM, Jake Luciani wrote: > Having worked at places where you get fired if software *attempts* to > contact outside world I understand th

Re: hintedhandoff in 1.0.3

Keys in HCF are nodes it has hints for. You can try forcing delivery to the node that still has hints. It's also possible that new hints were created (because that node timed out some writes) during the delivery of the first ones. On Tue, Nov 15, 2011 at 3:42 AM, Radim Kolar wrote: > Same probl

This brings up a nice possibility also for businesses to have Cassandra outsourced monitoring service(s)/solutions(s) from ring infrastructure perspective. Any chance the URL Cassandra posts information too can be configurable also? Maybe even an abstract class so others can extend it and the fir

Having worked at places where you get fired if software *attempts* to contact outside world I understand the concerns. However, if it's opt-in via config file and requires a restart then there is no reason why it should be a concern. On Wed, Nov 16, 2011 at 3:29 AM, Zhu Han wrote: > On Wed, No

I think it is a very good idea to gather such information and to make it easy for the users who want to or don't care and to consider the "twitchiness" as well. How about putting the reporting code in a separate module/jar and report statistics if the jar is there and don’t if it is not (similar

Re: How is Cassandra being used?

I've read through the thread and have a few comments and and idea.  1) I can understand a preference for opt in 2) As a user I would have probably opted in every time I hit a performance issue 3) Opt in may well be skewed to poorer use cases or hardware issues 4) There is a trust gap that needs to
