>> Cassandra stores hints for the lowest of gc_grace_seconds and max_hint_window_in_ms Was this a tough design decision or just a bug? It is certainly very surprising behavior. Everything that I've read leads me to believe that gc_grace_seconds was only intended to affect the treatment of

Re: Batch size warnings

Hi Voytek, I think the way you are using it is definitely the canonical way. Unfortunately, as you learned, there are some gotchas. We tried substantially increasing the batch size and it worked for a while, until we reached new scale, and we increased it again, and so forth. It works, but soon

Re: Why does `now()` produce different times within the same query?

Getting the same TimeUUID values might be a major problem. Getting two different TimeUUIDs that at least have time component would not be a major problem as this is the main case today. Getting different time components is actually the corner case, and it is a corner case that breaks

Re: Java Collections.emptyList inserted as null object in cassandra

It is not possible. Internally Cassandra flattens your data out into a set of key-value-pairs. All collection types, including lists, are nothing more than a thin layer of schema over a clustered set of key-value-pairs, so on disk there is no difference between an empty list and a list that

Re: Cannot mix counter and non counter columns in the same table

For counter tables, non-counter types are of course allowed in the primary key. Counters would be meaningless otherwise. Thanks, Cody On Nov 1, 2016 7:00 AM, "Ali Akhtar" wrote: > In the documentation for counters: > >

Re: Problems with schema creation

Hi Josh, I too have had this issue on several clusters I manage, particularly when making schema changes. The worst part is, those nodes don't restart, and the tables can't be dropped. Basically you have to rebuild your whole cluster which often takes down time. Others have seen this on 3.0.x and
