Lampros Smyrnaios e975bec911 - Add Prometheus and Grafana which help measuring various metrics for the Controller's health and performance. 
- Fix Docker config still using the old (now removed) "application.properties" file.
- Simplify the process of building and running the docker image; Now we use docker compose to run the Controller, along with the Prometheus and Grafana. Also, now it is not requested from the user to login and push the image (this may change in the future).

Lampros Smyrnaios 003c0bf179 - Add support for excluding specific datasources from being crawled. These datasources may be aggregated through bulk-imports, by other pieces of software. Such a datasource is "arXiv.org". 
- Fix an issue, where the "datasource-type" was retrieved instead of the "datasource-name".
- Polish the "findAssignmentsQuery".

Lampros Smyrnaios 49fefefafd - Refactor the payloads-statistics-code and provide two endpoints: "getNumberOfPayloadsAggregatedByService", which returns the number of payloads aggregated only by the PDF-Aggregation-Service, and the "getNumberOfAllPayloads", which returns the number of all payloads existing in the database, even the ones aggregated in the past, by other pieces of software.

- Code polishing.
 2022-12-09 12:46:06 +02:00
Lampros Smyrnaios 0209d24068 - Change the parquet compression from "Snappy" to "Gzip", as there is an unhandleable exception when the app is running inside a Docker Container and uses the "Snappy" compression.

- Update dependencies.
 2022-11-30 16:28:39 +02:00
Lampros Smyrnaios 6226e2298d - Upgrade the results-loading process: Instead of making thousands of sql-insert requests to Impala now we write the results to parquet files, upload them to HDFS and then import the data into the Impala tables with just 2 requests. This results in a huge performance improvement. 
One side effect of using the parquet-files, is that the timestamps are now BIGDECIMAL numbers, instead of "Timestamp" objects, but, converting them to such objects is pretty easy, if we ever need to do it.
- Code polishing.

 2022-09-15 23:12:05 +03:00
Lampros Smyrnaios 3e8f9c6074 Update the "UriBuilder.java" to be able to acquire the running port of the server, in case the port-number was initially set to "random" (0).

Lampros Smyrnaios 9b95eebb6c - Remove the obsolete "parenthesis" and "increasing duplicate-num" from the full-texts' names, before sending them to the S3-Object-Store. They now end with the "file-hash", so it is guaranteed that they will be unique. The Worker continues to produce the previous kind of names, without any disturbance.

 2022-04-11 21:15:22 +03:00
