+# sync-api
+
+The sync-api service is used in the [Bigpicture](https://bigpicture.eu/) project.
+
+## Service Description
+
+The sync service facilitates replication of data and metadata between the nodes in the consortium.
+
+When enabled the service will perform the following tasks:
+
+1. Upon receiving a POST request with JSON data to the `/dataset` route.
+   1. Parse the JSON blob and validate it against the `file-sync` schema.
+   2. Build and send messages to start ingestion of files.
+   3. Build and send messages to assign stableIDs to files.
+   4. Build and send messages to map files to a dataset.
+
+## Configuration
+
+There are a number of options that can be set for the sync service.
+These settings can be set by mounting a yaml-file at `/config.yaml` with settings.
+
+ex.
+
+```yaml
+log:
+  level: "debug"
+  format: "json"
+```
+
+They may also be set using environment variables like:
+
+```bash
+export LOG_LEVEL="debug"
+export LOG_FORMAT="json"
+```
+
+### Service settings
+
+- `SYNC_API_PASSWORD`: password for the API user
+- `SYNC_API_USER`: User that will be allowed to send POST requests to the API
+
+### RabbitMQ broker settings
+
+These settings control how sync connects to the RabbitMQ message broker.
+
+- `BROKER_HOST`: hostname of the rabbitmq server
+- `BROKER_PORT`: rabbitmq broker port (commonly `5671` with TLS and `5672` without)
+- `BROKER_EXCHANGE`: exchange to send messages to
+- `BROKER_USER`: username to connect to rabbitmq
+- `BROKER_PASSWORD`: password to connect to rabbitmq
+- `BROKER_PREFETCHCOUNT`: Number of messages to pull from the message server at the time (default to 2)
+
+The default routing keys for sending ingestion, accession and mapping messages can be overridden by setting the following values:
+
+- `SYNC_API_ACCESSIONROUTING`
+- `SYNC_API_INGESTROUTING`
+- `SYNC_API_MAPPINGROUTING`
+
+### Logging settings
+
+- `LOG_FORMAT` can be set to “json” to get logs in json format. All other values result in text logging
+- `LOG_LEVEL` can be set to one of the following, in increasing order of severity:
+    - `trace`
+    - `debug`
+    - `info`
+    - `warn` (or `warning`)
+    - `error`
+    - `fatal`
+    - `panic`
