+Steps to deploy a new Data Services API version :

- Deploy new version of geocoder API to all servers
- Update the server user using: ALTER EXTENSION cdb_geocoder_server UPDATE TO '<CURRENT_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": 26739, "sentinel_master_id": "mymaster", "timeout": 0.1, "redis_db": 5}`
