# Recos-Injector
|
|
|
|
Recos-Injector is a streaming event processor used to build input streams for GraphJet-based services. It is a general-purpose tool that consumes arbitrary incoming event streams (e.g., Fav, RT, Follow, client_events, etc.), applies filtering, and combines and publishes cleaned up events to corresponding GraphJet services. Each GraphJet-based service subscribes to a dedicated Kafka topic, and Recos-Injector enables GraphJet-based services to consume any event they want.

|
|
## How to run Recos-Injector server tests
|
|
|
|
You can run tests by using the following command from your project's root directory:
|
|
|
|
$ bazel build recos-injector/...
|
|
$ bazel test recos-injector/...
|
|
|
|
## How to run recos-injector-server in development on a local machine
|
|
|
|
The simplest way to stand up a service is to run it locally. To run
|
|
recos-injector-server in development mode, compile the project and then
|
|
execute it with `bazel run`:
|
|
|
|
$ bazel build recos-injector/server:bin
|
|
$ bazel run recos-injector/server:bin
|
|
|
|
A tunnel can be set up in order for downstream queries to work properly.
|
|
Upon successful server startup, try to `curl` its admin endpoint in another
|
|
terminal:
|
|
|
|
$ curl -s localhost:9990/admin/ping
|
|
pong
|
|
|
|
Run `curl -s localhost:9990/admin` to see a list of all available admin endpoints.
|
|
|
|
## Querying Recos-Injector server from a Scala console
|
|
|
|
Recos-Injector does not have a Thrift endpoint. Instead, it reads Event Bus and Kafka queues and writes to the Recos-Injector Kafka.
|
|
|
|
## Generating a package for deployment
|
|
|
|
To package your service into a zip file for deployment, run:
|
|
|
|
$ bazel bundle recos-injector/server:bin --bundle-jvm-archive=zip
|
|
|
|
If the command is successful, a file named `dist/recos-injector-server.zip` will be created.
