Enabling Redis protocol with Ignite
Igniters,
I was thinking on enabling Redis protocol with Ignite [1] so that any Redis client can use Ignite transparently.
Currently I have two ideas.
1. Implement it as a core functionality by adding GridRedisProtocol and appropriate commands/handlers, similarly to how it is done with REST and memcached, and use TCP binary protocol of the current implementation. For this I will probably have to do some refactoring in ignite/internal/processors/rest by creating ignite/internal/processors/ext to have other external protocols, like
ignite/internal/processors/ext `-- rest `-- memcached `-- redis
2. Implement it as an external module that is started on a local machine in a client mode by a user, interpreting Redis commands and sending to the Ignite cluster.
To be consistent with REST and memcached implementations, I prefer the 1st approach. Any objections or advice?
Another question -- at first glance memcached protocol is implemented as a part of REST implementation. For instance, GridTcpRestParser is essentially a memcached parser. Should it be refactored?

Roman, if you can implement it within a couple of months, it will be great.
I also think this feature is big enough to warrant a new branch. This way
we can all do periodic reviews and provide comments.

Yakov,
Thanks for the pointers, that's exactly what I needed.
RESP (REdis Serialization Protocol) is not that complex, but depending on my other tasks it may take a month or two. I plan to implement the integration iteratively starting with the most used generic commands.If you need it earlier, someone else can pick the ticket, or we can create a branch to collaborate.

As far as I remember TcpRestParser switches the correct mode on as soon as
it receives the first message over the connection. You can try adding
Redis mode to it. Is that what you ask for?

Roman,
I like the idea! How complex is the protocol implementation? How long will
it take to implement?
As far as I remember TcpRestParser switches the correct mode on as soon as
it receives the first message over the connection. You can try adding
Redis mode to it. Is that what you ask for?
