The goal of sider is to build a redis-like kv store that scales using nvme ssd while maintaining similar speeds.

sider has developed its own framework called "pump" to handle asynchronous and concurrent logic. This is an implementation of c++ std::execution(p2300).

• For learn more about p2300, see here;
• For a standard implementation of the p2300, see here.

sider uses spdk to implement kernel bypass technology, taking full advantage of nvme's concurrency to speed up io.

• For learn more about spdk, see here;
• In the function apply you can see how to combine asynchronous and concurrent tasks using the operators provided by pump.

sider is still in development, not yet tested or used.

• basic std::execution framework
• spdk-based io
• basic kv functions (get,put,scan)
• ycsb test and iops reaches hardware limit.
• batch
• io_uring-based network
• cuda support
• cold and hot data separation
