The team behind the KVM hypervisor and the OSv unikernel is moving up the stack. The Seastar platform enables extreme high-throughput, low-latency applications on Linux, and can make existing real-world workloads run completely asynchronously.
Seastar uses shared-nothing data structures that eliminate costly locking between CPUs, and a dedicated user-space TCP implementation that runs on DPDK. These radical changes in the server design translate into 5X-10x performance gain while preserving all of the Cassandra goodies.
The speaker is the co-founder and CEO of ScyllaDB.
