Venice Multi-Datacenter Docker Quickstart

Follow this guide to set up a multi-datacenter venice cluster using docker images provided by Venice team.

Step 1: Install and set up Docker Engine 

Follow https://docs.docker.com/engine/install/ to install docker and start docker engine

Step 2: Download docker-compose-multi-dc-setup.yaml file 

wget https://raw.githubusercontent.com/linkedin/venice/main/docker/docker-compose-multi-dc-setup.yaml

Step 3: Run docker compose to bring up Venice multi-colo setup 

docker-compose -f docker-compose-multi-dc-setup.yaml up -d

Step 4: Access venice-client container’s bash shell 

docker exec -it venice-client /bin/bash

Step 5: Make sure that you’re in /opt/venice directory 

# pwd
/opt/venice
# if not change current working directory to /opt/venice
cd /opt/venice

Step 6: Create a store

Note: If you change the store name from test-store to something else, you will have to modify /opt/venice/sample-data/multi-dc-configs/batch-push-job.properties and /opt/venice/sample-data/multi-dc-configs/inc-push-job.properties to use the provided store name.

./create-store.sh http://venice-controller.dc-parent.venicedb.io:5555 venice-cluster0 test-store sample-data/schema/keySchema.avsc sample-data/schema/valueSchema.avsc

Step 7: Let’s add a dataset to the store using batch push 

./avro-to-json.sh sample-data/batch-push-data/kv_records.avro
Run a push job 
./run-vpj.sh sample-data/multi-dc-configs/batch-push-job.properties
Fetch data from dc-0 
./fetch.sh http://venice-router.dc-0.venicedb.io:7777 test-store 90 # should return a value
./fetch.sh http://venice-router.dc-0.venicedb.io:7777 test-store 100 # should return a value
./fetch.sh http://venice-router.dc-0.venicedb.io:7777 test-store 110 # should return null
./fetch.sh http://venice-router.dc-0.venicedb.io:7777 test-store 120 # should return null
Fetch data from dc-1 
./fetch.sh http://venice-router.dc-1.venicedb.io:7777 test-store 90 # should return a value
./fetch.sh http://venice-router.dc-1.venicedb.io:7777 test-store 100 # should return a value
./fetch.sh http://venice-router.dc-1.venicedb.io:7777 test-store 110 # should return null
./fetch.sh http://venice-router.dc-1.venicedb.io:7777 test-store 120 # should return null

Step 8: Let’s update some existing records in the dataset and add few new records using incremental push 

./avro-to-json.sh sample-data/inc-push-data/kv_records_v1.avro
Run incremental push job 
./run-vpj.sh sample-data/multi-dc-configs/inc-push-job.properties
Fetch data from dc-0 
./fetch.sh http://venice-router.dc-0.venicedb.io:7777 test-store 90 # should return an unchanged value
./fetch.sh http://venice-router.dc-0.venicedb.io:7777 test-store 100 # should return an updated value
./fetch.sh http://venice-router.dc-0.venicedb.io:7777 test-store 110 # should return inserted value
./fetch.sh http://venice-router.dc-0.venicedb.io:7777 test-store 120 # should return null
Fetch data from dc-1 
./fetch.sh http://venice-router.dc-1.venicedb.io:7777 test-store 90 # should return an unchanged value
./fetch.sh http://venice-router.dc-1.venicedb.io:7777 test-store 100 # should return an updated value
./fetch.sh http://venice-router.dc-1.venicedb.io:7777 test-store 110 # should return inserted value
./fetch.sh http://venice-router.dc-1.venicedb.io:7777 test-store 120 # should return null

Step 9: Exit from the venice-client container 

# type exit command on the terminal or use cntrl + c
exit

Step 10: Teardown the cluster 

docker-compose -f docker-compose-single-dc-setup.yaml down
