Scylla: ScyllaDB combines with SPDK

[hellowaywewe]

Hi,
My name is Helloway. I am a new one in ScyllaDB.

I am studying SPDK at present. SPDK as a high performance kit provides a user space, polled-mode, asynchronous, lockless NVMe driver for storage acceleration on the backend. However, SPDK only supports the acceleration of block storage, so I put forward a proposal on [blobkv] (https://trello.com/b/P5xBO7UR/things-to-do) which supports kv storage.
we know ScyllaDB is a column-based NOSQL database. Can we use the ScyllaDB to provide the interface of KV and write data directly to the local disk with SPDK？

Can anyone offer some answers?

Thx,

Helloway

This is highly interesting and we thought about it in the past.
Today Scylla relies on a filesystem but we do consider a direct, hardware,
K/V interface

maybe it's more efficient to combine scylla with specific storage solution like nvme ssd + 25G rdma + spdk

Scylla prefers excellent hardware but can run on small, old machines too.
The rule of the thumb is first
to scale up and have a large, fast server.
