The later includes the former and in addition to `seastar::format()`,
`print.hh` also provides helpers like `seastar::fprint()` and
`seastar::print()`, which are deprecated and not used by scylladb.
Previously, we include `seastar/core/print.hh` for using
`seastar::format()`. and in seastar 5b04939e, we extracted
`seastar::format()` into `seastar/core/format.hh`. this allows us
to include a much smaller header.
In this change, we just include `seastar/core/format.hh` in place of
`seastar/core/print.hh`.

Instead of lengthy blurbs, switch to single-line, machine-readable
standardized (https://spdx.dev) license identifiers. The Linux kernel
switched long ago, so there is strong precedent.
Three cases are handled: AGPL-only, Apache-only, and dual licensed.
For the latter case, I chose (AGPL-3.0-or-later and Apache-2.0),
reasoning that our changes are extensive enough to apply our license.
The changes we applied mechanically with a script, except to
licenses/README.md.
Closes#9937
This patch adds support for 2 hash commands HDEL and HGETALL.
Internally it introduces the hashes_result_builder class to
read hashes and stored them in a std::map.
Other changes:
- one exception return string was fixed
- tests now use pytest.raises

If we switch to using std::string we have to handle begin and end
returning iterators.

following commit:

The new error message is part of Redis 4.0, released in 2017, so let's
switch Scylla to use the new one.
Message-Id: <20200211133946.746-1-penberg@scylladb.com>
Support to delete multiple keys in one DEL command.
The feature of returning number of the really deleted keys is still not supported.
Return empty string to client for GET command when the required key is not exists.
Fixes: #5334

Scylla has advantage and amazing features. If Redis build on the top of Scylla,
it has the above features automatically. It's achived great progress
in cluster master managment, data persistence, failover and replication.
The benefits to the users are easy to use and develop in their production
environment, and taking avantages of Scylla.
Using the Ragel to parse the Redis request, server abtains the command name
and the parameters from the request, invokes the Scylla's internal API to
read and write the data, then replies to client.
