Spruce

High Performance Distributed Key-value Database

We use many kinds of high performance algorithms

• High performance hash storage algorithm
  • Blizzard Hash
  • Fast Search Algorithms
• Consistent hash slot
• message queue (ring architecture)

Usage

create single server

1. create app.go
2. write it like this

   conf := make([]spruce.DNode, 1)
   conf[0] = spruce.DNode{
           Name:     "master",
           Ip:       "127.0.0.1:6999",
           Weigh:    2,
           Password: "",
   }
   spruce.StartSpruceDistributed(spruce.Config{
           ConfigType:    spruce.MEMORY,
           DCSConfigFile: "",
           DNode:         conf,
           Addr:          ":6998", 
                   MaxSlot:        4096
           NowIP:         "127.0.0.1:6999",
           KeepAlive:     false,
           IsBackup:      false,
   })

3. connect it (two)

   1. gRpc

      service Operation {
        rpc Get(OperationArgs) returns (Result){}
        rpc Set(OperationArgs) returns (SetResult){}
        rpc Delete(OperationArgs) returns (DeleteResult){}
      }
      message OperationArgs{
       bytes Key =1;
       bytes Value =2;
       int64 Expiration=3;
      }
      message Result{
       bytes Value=1;
      }

   2. achieve protocol
