Sync-Rep (Synchronous replication using standalone Redis)

2 Configurations

• (i) Sync-Rep (1): two VMs, one as the Redis leader and the other as a follower; and
• (ii) Sync-Rep (2): three VMs, one as the Redis leader and the other two as followers.
• Note: We run clients on follower VMs to force the system to have one RTT so that it’s compatible with SMR-based approach.

To Run

1. Start VMs

   • Start appropriate number of VMs according to Sync-Rep (1) or (2).
   • OS Assumption: Ubuntu 16.04

2. On each VM, complete the following steps:

   • Clone Rabia repository

     sudo su
     mkdir -p ~/go/src && cd ~/go/src
     git clone https://github.com/haochenpan/rabia.git

   • Install Rabia and its dependencies (Dependencies of Sync-Rep are included in Rabia's installation script.)

     cd ./rabia/deployment
     . ./install/install.sh

   • Clone Sync-Rep repository

     cd ~/go/src
     git clone https://github.com/YichengShen/redis-sync-rep.git
     cd redis-sync-rep

   • Configure IP of master VM

     • In config.yaml, change 'MasterIp' to the IP of your master VM.

   • Start Redis server: You could configure the current VM either as a master or a replica.

     • configure as master

       . ./deployment/startRedis/startServer.sh

     • configure as replica

       . ./deployment/startRedis/startServer.sh replica

   • Adjust parameters related to batching in config.yaml

     • Change ‘NClients’ and ‘ClientBatchSize’.

3. From one of the client VMs, run the main program

   go run main.go

   The program will run according to the configuration file and print out the results which will also be saved in the logs folder.
