# stockercm

Sentiment processor using `Cloud Functions`, `Cloud PubSub`, `Natural Language Processing API`, and `Cloud Dataflow`.

## Setup

Create PubSub topics

```shell

gcloud pubsub topics create stocker-source

gcloud pubsub topics create stocker-processed

```

Creating BigQuery content table

```shell

bq mk stocker

bq query --use_legacy_sql=false "

  CREATE OR REPLACE TABLE stocker.content (

    symbol STRING NOT NULL,

    cid STRING NOT NULL,

    created TIMESTAMP NOT NULL,

    author STRING NOT NULL,

    lang STRING NOT NULL,

    source STRING NOT NULL,

    content STRING NOT NULL,

    magnitude FLOAT64 NOT NULL,

    score FLOAT64 NOT NULL,

    retweet BOOL NOT NULL

)"

```

Create Cloud Dataflow job to drain processed topic to BigQuery

```shell

gcloud dataflow jobs run stocker-processed-to-bq-pump \

  --gcs-location gs://dataflow-templates/latest/PubSub_to_BigQuery \

  --parameters topic=projects/${GCP_PROJECT}/topics/stocker-processed,\

    table=${GCP_PROJECT}:stocker.content \

  --region us-central1

```

## Deploy

Deploy a Cloud Function to process the events from `stocker-source` topic and push results to `stocker-processed`.

```shell

gcloud functions deploy stocker-process \

  --entry-point ProcessorSentiment \

  --set-env-vars "PID=${GCP_PROJECT}" \

  --memory 256MB \

  --region us-central1 \

  --runtime go112 \

  --trigger-topic stocker-source \

  --timeout=300s

```

## Cleanup

Delete the Cloud Function

```shell

gcloud functions delete stocker-process --region us-central1

```

Delete the Cloud Dataflow job

```shell

gcloud dataflow jobs cancel stocker-processed-to-bq-pump --region us-central1

```
