rainbow-sync

A daemon that synchronizes IRIS hub data for the Rainbow wallet backend

Structure

  • conf: config of project
  • block: parse asset detail and tx function module
  • model: mongodb script to create database
  • task: main logic of sync-server, sync data from blockChain and write to database
  • db: database model
  • msgs: tx msgs model
  • lib: cdc and client pool functions
  • utils: common functions
  • main.go: bootstrap project

SetUp

Database

Use Mongodb to store IRIS hub data

Build And Run

  • Build: make all
  • Run: make run
  • Cross compilation: make build-linux

Run with docker

You can run application with docker.

Image

  • Build Rainbow-sync Image
docker build -t rainbow-sync .
  • Run Application
docker run --name rainbow-sync \&
-v /mnt/data/rainbow-sync/logs:/root/go/src/github.com/irisnet/rainbow-sync/logs \&
-e "DB_ADDR=127.0.0.1:27217" -e "DB_USER=user" \&
-e "DB_PASSWD=password" -e "DB_DATABASE=db_name"  \&
-e "SER_BC_FULL_NODES=tcp://localhost:26657,..." rainbow-sync

Environment Params

DB_ADDR string "" db addr 127.0.0.1:27017,127.0.0.2:27017...
DB_USER string "" db user user
DB_PASSWD string "" db passwd password
DB_DATABASE string "" database name db_name
SER_BC_FULL_NODES string tcp://localhost:26657 iris full node rpc url tcp://localhost:26657, tcp://127.0.0.2:26657
WORKER_NUM_EXECUTE_TASK string 30 number of threads executing synchronization TX task 30
WORKER_MAX_SLEEP_TIME string 120 the maximum time (in seconds) that synchronization TX threads are allowed to be out of work 120
BLOCK_NUM_PER_WORKER_HANDLE string 50 number of blocks per sync TX task 50
BEHIND_BLOCK_NUM string 0 wait block num to handle tx 0
PROMETHOUS_PORT string 9090 promethous metrics server port 9090
  • Remarks

    • synchronizes block chain data from specify block height(such as:17908 current time:1576208532)

      At first,stop the rainbow-sync and create the task. Run:

       db.sync_iris_task.insert({'start_height':NumberLong(17908),'end_height':NumberLong(0),'current_height':NumberLong(0),'status':'unhandled','last_update_time':NumberLong(1576208532)})
    Then,start the rainbow-sync.
