Hello, https://apacheignite.readme.io/docs/memcached-support
I have run php and ruby codes according to the page above, and perl and golang ones with library using memcache binary protocol, but only the php codes work. Especially, I require a piece of workable ruby codes. My test shows that it can read, but not write. <client side> irb(main):001:0> dc = Dalli::Client.new('10.1.14.221:11211') => #<Dalli::Client:0x000000000c3a0eb0 @servers=["10.1.14.221:11211"], @options={}, @ring=nil> irb(main):002:0> dc.get('foo') Dalli::Server#connect 10.1.14.221:11211 => "bar" irb(main):003:0> dc.set('foo', 'bar') 10.1.14.221:11211 failed (count: 0) EOFError: end of file reached #<Dalli::NetworkError: Socket operation failed, retrying...> retrying request with new server Dalli::Server#connect 10.1.14.221:11211 10.1.14.221:11211 failed (count: 0) EOFError: end of file reached #<Dalli::NetworkError: Socket operation failed, retrying...> (infinite loop) <server side> [/opt/apache-ignite-fabric-2.5.0-bin]$ less work/log/ignite-5fc8eef4.0.log ......
