Subject Re: Enabling Redis protocol with Ignite
Date Thu, 24 Mar 2016 01:13:47 GMT
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.

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?
