Configuration changes in Cassandra 1.2

Cassandra 1.2 introduces new and improved configuration options, including separate timeouts for single-row reads, range scans, writes, truncation, and miscellanea. The update also adds the ability to handle request overload by dropping requests that have timed out before being processed. Additionally, SSL support is extended to client connections, and bloom filters are configured on a per-table basis with different false positive chances for leveled and size-tiered compaction strategies. These changes provide more fine-grained control and improved performance in Cassandra 1.2.
