druid's Introduction

Container Druid

How to use the image

To start the container

docker run -d --rm -p 8888:8888 --name druid swal4u/druid:v0.15.1.2

To stop the container

docker stop druid

If you want to have data persistence, you must declare volume folder.

How to have exact COUNT Distinct without approximation

docker run -d --rm -p 8888:8888 -p 8082:8082 -v $PWD/broker/runtime.properties:/usr/local/druid/conf/druid/single-server/micro-quickstart/broker/runtime.properties  --name druid swal4u/druid:v0.15.1.2

My new file runtime.properties contains additional lines at the end of original file.

# SQL properties
druid.sql.planner.useApproximateCountDistinct=false

curl -XPOST -H'Content-Type: application/json' http://127.0.0.1:8082/druid/v2/sql/ -d @count_page.json
