 The Controller's Application receives requests coming from the [Workers](https://code-repo.d4science.org/lsmyrnaios/UrlsWorker) , constructs an assignments-list with data received from a database and returns the list to the workers.<br>
 Then, it receives the "WorkerReports", it requests the full-texts from the workers, in batches, and uploads them on the S3-Object-Store. Finally, it writes the related reports, along with the updated file-locations into the database.<br> 
-The database used is the [Impala](https://impala.apache.org/).<br>
+<br>
+It can also process **Bulk-Import** requests, from compatible data sources, in which case it receives the full-text files immediately, without offloading crawling jobs to Workers.<br>
+<br>
+For interacting with the database we use [Impala](https://impala.apache.org/).<br>

+- "**getNumberOfAllPayloads**" endpoint: **http://\<IP\>:<PORT>/api/stats/getNumberOfAllPayloads** <br>
   This endpoint returns the total number of payloads existing in the database, independently of the way they were aggregated. This includes the payloads created by other pieces of software, before the PDF-Aggregation-Service was created.
-- "**getNumberOfPayloadsAggregatedByService**" endpoint: **http://<IP>:<PORT>/api/stats/getNumberOfPayloadsAggregatedByService** <br>
+- "**getNumberOfPayloadsAggregatedByService**" endpoint: **http://\<IP\>:<PORT>/api/stats/getNumberOfPayloadsAggregatedByService** <br>
   This endpoint returns the number of payloads aggregated by the PDF-Aggregated-Service itself. It excludes the payloads aggregated by other methods, by applying a Date-filter for the records created in 2021 or later.
-- "**getNumberOfPayloadsForDatasource**" endpoint:  **http://<IP>:<PORT>/api/stats/getNumberOfPayloadsForDatasource?datasourceId="givenDatasourceId"** <br>
+- "**getNumberOfPayloadsForDatasource**" endpoint:  **http://\<IP\>:<PORT>/api/stats/getNumberOfPayloadsForDatasource?datasourceId=\<givenDatasourceId\>** <br>
   This endpoint returns the number of payloads which belong to the datasource specified by the given datasourceID.
-- "**getNumberOfRecordsInspected**" endpoint: **http://<IP>:<PORT>/api/stats/getNumberOfRecordsInspected** <br>
+- "**getNumberOfRecordsInspected**" endpoint: **http://\<IP\>:<PORT>/api/stats/getNumberOfRecordsInspected** <br>
   This endpoint returns the number of records inspected by the PDF-Aggregation-Service.

 Implementation notes:
 - For transferring the full-text files, we use Facebook's [**Zstandard**](https://facebook.github.io/zstd/) compression algorithm, which brings very big benefits in compression rate and speed.
