@jcy1001 I would like to help you with your question/request/issue. But unfortunately, I don't know the language and Google Translate said I hope to increase the stream function of redis and realize the simple mq function which I didn't fully understand.

hi, redis has stream function in t_stream.c , redis7.0 has xgroupCreate like command , but our project not implemented, i only find xadd xdel xinfo ..in cmd_stream.cc, thanks ~

jcy1001 commented 1 year ago

this is our project

REDIS_REGISTER_COMMANDS(MakeCmdAttr("xadd", -5, "write", 1, 1, 1), MakeCmdAttr("xdel", -3, "write", 1, 1, 1), MakeCmdAttr("xlen", -2, "read-only", 1, 1, 1), MakeCmdAttr("xinfo", -2, "read-only", 0, 0, 0), MakeCmdAttr("xrange", -4, "read-only", 1, 1, 1), MakeCmdAttr("xrevrange", -2, "read-only", 1, 1, 1), MakeCmdAttr("xread", -4, "read-only", 0, 0, 0), MakeCmdAttr("xtrim", -4, "write", 1, 1, 1), MakeCmdAttr("xsetid", -3, "write", 1, 1, 1))

this is redis XACK XADD XCLAIM XDEL XGROUP XINFO XLEN XPENDING XRANGE XREAD XREADGROUP XREVRANGE XTRIM

We are implementing features to be compatible with Redis 7.0, it may need some time. I can drive this task when i'm free.

@jcy1001 Yes, you are right, currently, consumer groups aren't implemented in Kvrocks.
