qos-service components

Detail

Scala based service that:

• streams endo-events from AWS kinesis
• filters for valid endo-events with qos attributes
• transforms events to qos streaming objects
• stores, sink, qos object to pipelineDB

setup

git clone /~https://github.com/kayvank/qos-service
sbt clean compile  // to build prject
sbt test // unit test
sbt it:test // integration test
sbt clean compile universal:packageBin // to generate an executable
sbt clean compile docker:publishLocal

To run the service locally

• install or run a dockerimage of pipelineDB
• configure piplelineDB
• set up environment variable for AWS credentials to point to kinesis stream
• build executable
• execute

pipelineDB

• pull down pipelineDB docker image:

docker run  -it --rm -v pgdata:~/var/lib/postgresql/data
docker run -d -p 5432:5432 -v pgdata:/Users/<MY_USER_NAME>/var/lib/postgresql/data pipelinedb/pipelinedb

• create ~/.pgpass for ease of login, see references for detail

0.0.0.0:5432:pipline:pipeline:pipeline

• create user & database

CREATE USER qos WITH PASSWORD 'qos' CREATEDB;
create database qos owner qos;

• DDL

create stream qos_stream (
 bitrate float,
 qos_startup_time float,
 qos_buffering_spinner_duration float,
 qos_buffering_spinner_events int,
 qos_buffering_at_end bool,
 video_id text, 
 video_url text, 
 is_ad bool,
 is_play bool, 
 region text,

 country text, 
 lat_lon point,
 platform text,
 app_version text,
 build_number text,
 device text,
 user_id text,
 is_anon bool,

);

• build executable

sbt clean compile universal:packageBin

• execute

cd ./target/universal
unzip qos-service-1.0.1.zip
cd qos-service-1.0.1
./bin/qos-service
