# Data Services API
The CARTO Data Services SQL API (server and client FTM)

### Deploy instructions
Steps to deploy a new Data Services API version :

- Deploy new version of dataservices API to all servers
- Update the server user using: ALTER EXTENSION cdb_dataservices_server UPDATE TO '<CURRENT_VERSION>';
- Update the python dependencies if needed: **cartodb_geocoder** and **heremaps**
- Add the needed config in the `cdb_conf` table:
  - `redis_metadata_config` and `redis_metrics_conf`
    - `{"sentinel_host": "localhost", "sentinel_port": 26379, "sentinel_master_id": "mymaster", "timeout": 0.1, "redis_db": 5}`
  - `heremaps_conf`
    - `{"app_id": "APP_ID", "app_code": "APP_CODE"}`
- Deploy the client to all the servers with the new version
- Deploy the editor with the new dataservices api version changed (https://github.com/CartoDB/cartodb/blob/master/app/models/user/db_service.rb#L18)
- Execute the rails task to update first the CartoDB team organizaton to test in production
  - `RAILS_ENV=production bundle exec rake cartodb:db:configure_geocoder_extension_for_organizations['team']`
- Check if all works perfectly for our team. If so, execute the rake tasks to update all the users and organizations:
  - `RAILS_ENV=production bundle exec rake cartodb:db:configure_geocoder_extension_for_organizations['', true]`
  - `RAILS_ENV=production bundle exec rake cartodb:db:configure_geocoder_extension_for_non_org_users['', true]`
- Freeze the generated SQL file for the version. Eg. cdb_dataservices_server--0.0.1.sql

### Local install instructions

- install data services geocoder extension 

    ```
    git clone git@github.com:CartoDB/data-services.git
    cd data-services/geocoder/extension
    sudo make install
    ```
    
- install observatory extension 

    ```
    git clone git@github.com:CartoDB/observatory-extension.git
    cd observatory
    sudo make install
    ```

- install server and client extensions
    
    ```
    cd client && sudo make install
    cd server/extension && sudo make install
    ```

- install python library

    ```
    cd server/lib/python/cartodb_services && python setup.py install
    ```

- install extensions in user database

    ```
    create extension cdb_geocoder;
    create extension plproxy;
    create extension observatory;
    create extension cdb_dataservices_server;
    create extension cdb_dataservices_client;
    ```

- add configuration for different services in user database


    ```
    # If sentinel is used:
      SELECT CDB_Conf_SetConf('redis_metadata_config', '{"sentinel_host": "localhost", "sentinel_port": 26379, "sentinel_master_id": "mymaster", "timeout": 0.1, "redis_db": 5}');
      SELECT CDB_Conf_SetConf('redis_metrics_config', '{"sentinel_host": "localhost", "sentinel_port": 26379, "sentinel_master_id": "", "timeout": 0.1, "redis_db": 5}');
      
    # If sentinel is not used
      SELECT CDB_Conf_SetConf('redis_metadata_config', '{"redis_host": "localhost", "redis_port": 26379, "sentinel_master_id": "", "timeout": 0.1, "redis_db": 5}');
      SELECT CDB_Conf_SetConf('redis_metrics_config', '{"redis_host": "localhost", "redis_port": 6379, "sentinel_master_id": "", "timeout": 0.1, "redis_db": 5}');
  
    SELECT CDB_Conf_SetConf('heremaps_conf', '{"geocoder": {"app_id": "here_geocoder_app_id", "app_code": "here_geocoder_app_code", "geocoder_cost_per_hit": "1"}, "isolines" : {"app_id": "here_isolines_app_id", "app_code": "here_geocoder_app_code"}}');
    SELECT CDB_Conf_SetConf('user_config', '{"is_organization": false, "entity_name": "<YOUR_USERNAME>"}')
    SELECT CDB_Conf_SetConf('mapzen_conf', '{"routing": {"api_key": "valhalla_app_key", "monthly_quota": 999999}, "geocoder": {"api_key": "search_app_key", "monthly_quota": 999999}}');
    SELECT CDB_Conf_SetConf('logger_conf', '{"geocoder_log_path": "/tmp/geocodings.log"}')
    SELECT CDB_Conf_SetConf('data_observatory_conf', '{"connection": {"whitelist": [], "production": "host=localhost port=5432 dbname=dataservices_db user=geocoder_api", "staging": "host=localhost port=5432 dbname=dataservices_db user=geocoder_api"}}')
    ```

- configure plproxy to point to the a database (you can use a specific database for the server or your same user)

    ```
     SELECT CDB_Conf_SetConf('geocoder_server_config', '{ "connection_str": "host=localhost port=5432 dbname=<SERVER_DB_NAME> user=postgres"}');
    ```

- configure the search path in order to be able to execute the functions without using the schema:

    ```
    ALTER ROLE "<USER_ROLE>" SET search_path="$user", public, cartodb, cdb_dataservices_client;
    ```
