Description
In Cassandra 0.7.X keyspace moved from the method signature of the get request to a thread local variable. I think there are several other thread local variables that could be added that would could give special performance characteristics. These would be set on the client and change how the server processes requests.
- nocache
Currently we have two applications, one of them is a range scan and cleanup application, the other is some of of our data is fed into the system through a batch process that is hours behind current. Especially in the case of the second program we get cache pollution all day long. this option would allow us to batch/back load without ruining caches. - norepair
This option would supersede the current read repair chance or work with it. Helpful if you know you may re-edit this column soon anyway - memtable read prefer
I know this idea is ify. For most use cases the column being read is inside your memtable newer versions will not exist on disk. This option means -if you find data in the memtable use that, otherwise look on disk.
