Lampros Smyrnaios 8f9786de09 Upgrade the algorithm for finding the previously-found fulltexts, based on their md5hash: 
- Use a single query with a list of the fileHashes, instead of thousands of singe-md5hash-check queries (run at most 6 in parallel) which require a lot of I/O.
- Avoid checking multiple times the same fileHash, in case it is related with multiple payloads.
- In case of a database-error, avoid completely losing the full-texts of that worker, instead, continue processing the full-texts.

Lampros Smyrnaios e4540e7f3c Handle the case when a urlReports-sublist does not have any payloads inside. 2024-03-12 14:25:00 +02:00
Lampros Smyrnaios e20c5d2146 - Add error-handling for the case when no payloads could be associated with a specific url which should have been in the hashMultiMap in "addUrlReportsByMatchingRecordsFromBacklog". 
- Fix not cloning the payload, before changing it and adding it in the "prefilledPayloads"-list; instead, an object-reference was used.

- Update dependencies.
 2024-01-15 12:57:33 +02:00

 2023-12-19 23:31:42 +02:00
Lampros Smyrnaios d90ad51609 Add the "shutdownAllWorkersGracefully" and "cancelShutdownAllWorkersGracefully" endpoints, in order to be able to shut them down at once and update them, without shutting down the whole Service. So in this case the bulk-import procedures will continue to work. 2023-11-29 16:45:58 +02:00
Lampros Smyrnaios d20c9a7d2e - Show the original exception thrown by the background-job, not the one thrown in the main-thread, which is useless, except from its message. 
- Reduce the interval for deleting the unhandled assignments to once every 3 days.
- Set the upcoming version.

 2023-11-27 18:19:53 +02:00
Lampros Smyrnaios 7f789b8ad0 - If we receive an "UnknownHostException" when uploading to the S3ObjectStore, then skip the current full-texts' batch to leave some time for the network to get unstuck. 
- Code polishing.
 2023-11-22 15:29:18 +02:00
Lampros Smyrnaios 9b1f2c4931 Improve performance and reduce memory usage of the "findAssignmentsQuery": 
- Reorder JOINs and predicates to reduce the computational cost.
- Remove the memory-costly "pu.url" predicates from the "where" clause, as the DB has no empty urls anymore.
 2023-10-31 15:59:48 +02:00
Lampros Smyrnaios db929d8931 - Add a scheduling job to delete assignments older than 7 days. These may be left behind when the worker throws a "SocketTimeoutException" before it can receive the assignments and process them. No workerReport gets created for those assignments. 
- Improve some log-messages.
- Code polishing.
 2023-10-30 12:29:54 +02:00

 2023-10-26 11:44:23 +03:00
Lampros Smyrnaios bdf834c439 - Refactor the "shutdown" script to do an orderly-shutdown, by default, by calling the "shutdownService" endpoint. In case a "force-shutdown" is needed, that can be requested with a cmd-argument. 
- Fix not updating the "UrlsController.numOfWorkers" correctly.
- Code polishing.
 2023-10-23 17:19:29 +03:00
Lampros Smyrnaios 0c7bf6357b - Improve performance in "FileUtils.addUrlReportsByMatchingRecordsFromBacklog()". 
- Make sure we remove the assignments of all "not-successful", old, worker-reports, even for the ones which failed to be renamed to indicate success or failure, or failed to be executed by the background threads (and thus never reached the renaming stage).
 2023-10-23 12:21:42 +03:00

 2023-10-19 11:59:37 +03:00

Lampros Smyrnaios fb2877dbe8 Upgrade the execution system for the backgroundTasks: 
- Submit each task immediately for execution, instead of waiting for a scheduling thread to send all gathered tasks (up to that point) to the ExecutorService (and block until they are finished, before it can start again).
- Hold the Future of each submitted task to a synchronized-list to check the result of each task at a scheduled time.
- Reduce the cpu-time to assure the Service can shut down, by checking if there are "actively" and "about-to-be-executed" tasks, at the same time. Instead of having to rely on the additional checking of the "shutdown"-status of each worker to verify that no active task exist.
- Improve the threads' shutdown procedure.
 2023-10-09 17:23:59 +03:00
Lampros Smyrnaios a354da763d - Improve some log-messages.

 2023-10-04 16:17:12 +03:00
Lampros Smyrnaios 7019f7c3c7 Improve aggregation speed, by generating additional "attempt" and "payload" records for the publications which are in the back-log and their url matches to one of the urls of the current payloads. 2023-10-04 15:43:31 +03:00
Lampros Smyrnaios b702cf4484 Upgrade the "findAssignmentsQuery": 
- Retrieve the assignments by checking only the publication-urls against the "attempt", "assignment" and "payload" tables, not the IDs. This change allow us to: a) avoid re-attempting urls which have already been attempted multiple times (by different id-url pairs), b) avoid aggregating urls which are already inside the "payload" or "assignment" tables, even when they are related with other IDs.
In the end, we only care about the urls when choosing which records should be aggregated.
- Improve performance by using the "anti join" operator, where it fits, in order to allow the engine to use the faster "hash" operations.
 2023-10-04 13:43:15 +03:00
Lampros Smyrnaios c9626de120 Handle the case when the "upload-file-to-S3" operation fails with a "ConnectException". In this case, all remaining upload operations for the files of that particular batch or segment, are canceled. 2023-10-04 13:01:13 +03:00

Lampros Smyrnaios 02bae38885 - Improve response-time to "getAssignments"-requests, by avoiding merging the parquet files of the "assignment" table, right after acquiring the assignments from the DB. They are already getting merged, when each assignments-batch is deleted after a workerReport has been processed. 
- Optimize code-positioning for unlocking the DB when done executing queries.
